Professional photographers know what they want in a camera. Above all, the camera
must be dependable—able to come through in shooting situations that are far less than
ideal… even in harsh environmental and handling conditions. The camera must be
responsive—reacting instantly to the photographer’s input… able to capture, within a
heartbeat, the image in the mind’s eye. It must provide a sophisticated feature set that
makes it versatile and adaptable and, yet, does not compromise operability. And, of course,
it must deliver image quality beyond reproach—which, in the digital era, means not only
noise-free detail, richness of color, and depth of tone, but also sufficient data density to
satisfy the widest range of output applications. Today, there is one Digital Single-LensReflex (DSLR) camera that meets these criteria as no other: the Canon EOS-1D Mark III.
Redesigned and re-engineered from the ground up, Canon’s newest flagship EOS is
destined to become the next "must have" DSLR for professionals.
At a blazing 10 frames per second (fps), the 10.1-megapixel Canon EOS-1D Mark III is
the world’s fastest DSLR camera (as of February 2007). It is nearly 20% faster than the
8.5 fps EOS-1D Mark II N that it replaces, and it is crushingly faster than anything else
with comparable resolution. While this speed will make great headlines, it is but a small
part of the repertoire of a stunning machine that sets new benchmarks in virtually every
category of professional DSLR performance and then creates new categories where pro
DSLR cameras have never gone. The sum is a camera that is the epitome of professional
excellence in every respect. It will go everywhere, do everything and appeal to (almost)
The EOS-1D Mark III is the product of a “reset to zero” design program. As the newest
camera in Canon’s 1-series, it inherits a legacy of strength, reliability, control, flexibility
and image quality that is second to none in the world of photography. When planning
for it began, Canon was in the enviable position of being able to identify every possible
aspect of professional DSLR performance that could be improved in some way. They
relied on their legendary manufacturing expertise to bring the new ideas to fruition.
The EOS-1D Mark III uses a new, 10.1-megapixel image sensor, designed and manufactured
by Canon on semiconductor manufacturing equipment that is also designed, manufactured
and maintained by Canon. The sensor uses Canon’s proprietary CMOS technology with
several significant advances. Canon has managed to increase the proportion of each
pixel that is sensitive to light, called the fill factor. For any given pixel size, the greater
the fill factor, the more light each pixel can capture, resulting in better color and less noise.
Needless to say, this is not off-the-shelf technology.
Canon has also found a way to reconfigure the microlenses that distribute light to individual
pixels. The spaces between them are smaller and the way light strikes the sensor is more
intelligent. The result is that less light is lost, again improving image quality. Some of the
benefit of this sophistication can be found in the new ISO range of the EOS-1D Mark III,
100 to 3200 with extensions to 50 and 6400, the last figure unimaginable in a DSLR
until now. Photographers will be amazed when they discover the high quality and low
noise of ISOs 3200 and 6400 on the 1D Mark III.
The beautiful signal from the sensor is sent via a very fast 8-channel readout to two new
DIGIC III imaging engines. In the past, one such device has always sufficed, but with the
EOS-1D Mark III, there was to be no compromise of either speed or image quality. The
Dual DIGIC III Image Processors perform parallel processing, common nowadays in serious
computers but unique among cameras, to speed through information. Their workload is
increased by the fact that the new sensor captures 14-bit depth color rather than 12.
The result, particularly because the 1D Mark III has the horsepower to handle these files,
is exquisite gradation, 16,384 levels per color rather than 4,096 at 12 bits. Even when
JPEGs (at 8 bits) are created, they are made from a superior file and the difference can be
seen. Prints made from 1D Mark III files are spectacular.
The dual processors make themselves known, too, in the burst performance of the
EOS-1D Mark III. Large size JPEGs at compression level 8 (of 10) can be fired in barrages
of 110 frames (at 10 frames per second with 10.1-megapixel files). RAW images can be
shot in bursts of 30. Paparazzi of the world, your new camera has arrived.
Canon has been an acknowledged leader in autofocus technology for many years. The
EOS-1D Mark III project presented Canon engineers with the opportunity to perform a
complete reconsideration of professional autofocus. The result is an entirely new Area
AF sensor that has 19 high-precision, cross-type AF points and 26 assist AF points. The
cross-type points are spread out, reaching even the extreme edges of the Area AF coverage
area. The logic of AF point selection has been reconsidered, too. Any of the cross-type
points can be manually selected, and they can be sorted into an outer group and an
inner group so you don’t have to cycle through 45 AF points any more to get to the one
you want to use. Micro adjustment of autofocusing accuracy is now possible, something
many pros didn’t even know they could wish for, but which they will adopt with great
enthusiasm. Even focus-tracking sensitivity is now adjustable.
Have you ever put your camera in a spot where it was hard to look through the finder?
Too high? Too low? Edge of a precipice? In the rafters at Madison Square Garden or on the
inside railing at Churchill Downs? Canon has the answer: a professional Live View system,
usable with camera only (you can see what the lens sees on the new, large 3.0-inch LCD
monitor), or by remote control, either with a wire from the camera to a computer (in a
studio, perhaps) or wirelessly with the new WFT-E2A Dedicated Wireless File Transmitter.
When a computer is involved, the newly updated EOS Utility 2.0 software (included with
the camera) takes care of just about everything—virtually real-time viewing, focusing,
exposure, composition, firing—the lot.
There’s much, much more: a professional, fully-integrated cleaning system, a new shutter
rated at 300,000 cycles, highlight tone priority, safety shift, a completely revised and
simplified set of controls and menus, a new recording format, a silent mode, a new
magnesium alloy mirror box, an intelligent new lightweight and compact battery… and
that’s not all. And, we can’t forget to talk about the value propositions that the EOS-1D
Mark III represents. The text that follows will tell you all about them.

The EOS-1D Mark III’s new, Canon-designed and
manufactured, APS-H-size, CMOS single-plate
sensor advances the state of the art in professional
DSLR sensor design. APS-H is the largest sensor
that can be imaged in one pass using cutting edge
semiconductor manufacturing technology. The
imaging area of the new CMOS sensor measures
28.1 x 18.7mm, appreciably larger than APS-C and
about the same size as the sensors in the
(Actual Size)
EOS-1D Mark II and Mark II N.
The lens magnification factor is 1.3x. Shadow noise at all comparable ISO speed settings
is 50% less than with the EOS-1D Mark II N. The sensor features high-speed signal reading
(approx. 10 fps), low power consumption, and Live View shooting.
New 10.1 Megapixel
Combining the superb image capture capabilities of the new sensor with advanced Dual
DIGIC III Image Processors, the EOS-1D Mark III offers the widest ISO range of any DSLR in
the world (as of February 2007). The standard range of 100–3200 can be extended to a
remarkable 50–6400.* More important, the low-noise performance at high ISO settings
makes the entire range usable in real-world shooting situations.
* CIPA standard output sensitivity. Recommended exposure index.
EOS-1D Mark II N/1Ds Mark II/5D
The EOS-1D Mark III sensor has 10.1 effective megapixels, a 25% increase over the 8.2
megapixels of the EOS-1D Mark II. Individual pixel size on the 1D Mark III’s sensor is 7.2µm,
the same size as the pixels of the EOS-1Ds Mark II.

Although the pixel size of the 1D Mark III is 1 micron smaller than the pixel size of the
EOS-1D Mark II and Mark II N, the photodiode size of both sensors is the same, thanks to
the optimized photodiode construction and more sophisticated processing of the 1D Mark III.
By optimizing the gap between the on-chip microlenses and improving the fill factor
(photodiode area divided by total pixel size) of each pixel, light-gathering efficiency has
been improved. Also, by optimizing the photodiode's structure, light-reception efficiency
has been improved. Additionally, the second-generation, on-chip noise removal circuit and
the noise reduction technology explained below combine to remove noise effectively.
This has enabled the EOS-1D Mark III to be the first EOS DSLR camera to have ISO 3200
as part of its standard ISO speed range. Dynamic range at low ISO speeds is about the
same with the 1D Mark III as it is with the EOS-1D Mark II and Mark II N despite the
1D Mark III’s increased resolution.
A second-generation, on-chip, noise-reduction circuit is provided. To achieve even less

noise, the EOS-1D Mark III has a new feed-through output amp that attains both high
speed and low noise. Low noise is also achieved with an improved manufacturing process,
an optimized pixel amp and an optimized reading circuit.
As with the EOS-1D Mark II N, single-line, 8-channel reading is
employed. With a faster output amp and optimized read circuit,
a continuous shooting speed of approximately 10 fps is attained.
To minimize the higher power consumption required by the faster
signal reading, the output amp's power consumption has been reduced. Also, as in the
EOS-1D Mark II N, during long exposures, power to the output amp is turned off and the
standard current driving the circuit is also cut off to save power. In addition, during Live
View shooting, the power distribution for the signal-reading operation is optimized for
more pinpoint power-saving control.
Previously, in front of the sensor, there was an infrared-absorption glass integrated with
a three-layer, optical crystal plate for point image separation. However, for the Self
Cleaning Sensor Unit, the infrared-absorption glass is now separate from the three-layer,
optical crystal plate. This makes the dust-shaking plate lighter, saving power and
making it easier to control.
Dichroic mirror
(Reflects infrared rays)
The infrared filter has a hybrid construction; it has an infraredabsorption glass with multiple coatings to reflect infrared and
ultraviolet rays, the same construction found in EOS-1D series
cameras. It effectively reduces red fringing and color casts caused
by reflections of the sensor surface. The low-pass filter for point
image separation has a phase plate (which converts linear polarization to circular polarization) sandwiched by two single crystal
plates. It is optimized for the sensor pitch so the light flux is
separated into the horizontal and vertical directions and the fine
horizontal- and vertical-line patterns are cleanly separated,
effectively reducing color artifacts such as moiré.

DIGIC II, a high-performance imaging engine that has been used since the EOS-1D Mark II
in 2004, has been a major feature of Canon digital cameras because of its very fine image
detail, natural color reproduction and high-speed signal processing. DIGIC III retains the
DIGIC II's basic concept and improves upon it with higher performance and faster speed.
To cope with the voluminous signal processing required by the EOS-1D Mark III’s 10.10
megapixels and top continuous shooting speed of 10 fps, Dual DIGIC III Image Processors
are incorporated for parallel signal processing. The CMOS sensor reads out to the dual
DIGIC III Image Processors simultaneously in 8 channels.
By having 2 processors handle the workload, image processing is now approximately
1.5x faster; Compact Flash™ access speed is now 1.3x faster, and SD card access is
now 2x faster compared to the EOS-1D Mark II N. The extra power of Dual DIGIC III Image
Processors has also allowed analog-to-digital conversion to improve from 12 to 14 bits
per channel, meaning that tonal gradation for RAW images is now divided into 16,384
separate levels per channel rather than 4,096. When saved as a 16-bit TIFF image, the
image retains the full range of tones obtained with 14 bits. Also, JPEG images, at 8 bits
per color, are generated from the 14-bit data. Tonal skipping is thereby reduced
substantially, improving gradation and overall image quality.

Noise reduction for long exposures is equivalent to that on the EOS-1D Mark II N. When
[C. Fn II-1; 1: Auto] is set, 1 sec. and longer exposures will undergo noise reduction
automatically, depending on the amount of noise detected in the image data. If [C. Fn II-1;
2: On] is set, all 1 sec. and longer exposures will undergo noise reduction.
Now, noise reduction for pictures taken at a high ISO speed is provided via [C. Fn II-2].
Although this feature works at all ISO speeds, it is especially effective for high ISO speeds.
At low ISO speeds, noise reduction is not really necessary. However, applying noise
reduction can reduce noise within shadow areas taken under low light.
Hilight Tone Priority
This new feature extends the dynamic range of highlights by about one stop and improves
gradation within highlight areas. By expanding the range from the correct exposure level
(18% gray) to the maximum allowable highlight level, the gradation from the grays to
the highlights becomes smoother and loss in highlight detail is minimized. If [C.Fn II-3;
1: Enable] is set, the settable ISO speed range will be ISO 200- 3200. The display will
show "2oo" with the zeros in smaller characters. Depending on shooting conditions,
noise in the shadow areas may increase slightly.

New sRAW Image Size
In addition to RAW, JPEG Large, Medium 1, Medium 2, and Small, the EOS-1D Mark III
features a new image size, sRAW or Small RAW. sRAW images have approximately
one-fourth the pixel count, 2.5 megapixels, and approximately half the file size of RAW
images. Just like regular RAW images, sRAW images can be adjusted and processed with
the provided software. The feature is expected to appeal to wedding photographers, for
example, who do not need full resolution for wedding candids but who do need the
postproduction control RAW offers.

Image Type
The EOS-1D Mark III incorporates the EOS Integrated Sensor Cleaning System, which is
a complete anti-dust system. It suppresses dust generation and dust adhering to the
sensor, removes dust and makes any remaining dust less noticeable.
• The shutter has been improved to generate less dust
• The body cap has also been improved to generate less dust
• The low-pass filter's anti-static charge surface prevents
attracting dust due to static charge
• The sensor unit is self-cleaning
• Dust Delete Data is obtained and appended to images.
• Manual cleaning of the imaging sensor is still an option
Self-Cleaning Sensor Unit
The new, compact Self-Cleaning Sensor Unit for the APS-H size imaging sensor has been
designed for the EOS-1D Mark III and is different from the EOS Digital Rebel XTi/400D
Digital's unit. (The Dust Delete Data specifications are the same as with the EOS Digital
Rebel XTi/400D Digital.) On the front infrared-absorption glass, two thin, single-layer
piezo-electric elements are attached. By applying ultrasonic vibration to the infraredabsorption glass, the adhering dust is shaken off. The removed dust particles are stuck
onto absorbent material around the infrared-absorption glass. Also, to prevent dust
from entering the sensor unit, the assembly is secured with sealing material around the
perimeter. Another camera maker vibrates an extra glass plate dedicated to dust removal.
Because the EOS-1D Mark III vibrates the infrared-absorption glass directly, the optical
performance is not degraded by an extra layer of glass and the unit can be kept compact.
The Self-Cleaning Sensor Unit can therefore be incorporated in a conventional size body.
Operation timing is either auto or manual. The default setting has the unit operating for
about 3.5 sec. whenever you turn the power switch ON or OFF. While the unit is operating,
the LCD monitor displays a logo indicating that sensor cleaning is being executed. If the
menu is set to [Auto cleaning: Disable], the auto cleaning is not executed.

When the menu is set to [Clean now], you can clean the sensor whenever you wish.
It takes about 4 sec. During the cleaning, ultrasonic vibration is applied to the infraredabsorption glass and the shutter is cocked three times so that the dust falls off the
infrared-absorption glass and any dust resettling on the shutter curtains is also shaken
off. During sensor cleaning, whether started automatically or manually, pressing the
shutter button halfway or pressing the Menu button will immediately terminate the
cleaning and the camera will be ready to shoot. Because the unit has very low power
consumption, cleanings do not significantly affect the number of possible shots, even
if the default Auto setting is selected.
To prevent the piezo-electric elements from overheating and to ensure proper cleaning,
the unit cannot operate again within 3 sec. of finishing operation. Also, if the unit operates
five times successively at intervals shorter than 10 sec., it will not operate again for 10 sec.
During the stoppage, the [Clean now] menu option cannot be selected.
Dust Delete Data
The position of dust particles adhering to the infrared absorption glass can be detected
and acquired as Dust Delete Data. This data is appended to the image data. The information is used by Digital Photo Professional (DPP) 3.0 to erase the dust spots on the image.
When you select the [Dust Delete Data] menu, the unit will first execute the cleaning
operation automatically. Then you can photograph a plain, white subject at infinity.
The Dust Delete Data will thereby be obtained. It is preferable that you shoot in the
aperture-priority AE mode at f/22. This same Dust Delete Data will then be appended
to images until it is updated again. If you change lenses, you should obtain the Dust
Delete Data again for best results. DPP erases the dust spots on the image by detecting
the position of the dust spots based on the appended Dust Delete Data. It will then
erase the dust spot only if it deems that doing so will be effective. If the [Clear all camera
settings] menu command is selected, all the camera settings will be cleared and the
Dust Delete Data will also be cleared.
AF System
Canon EOS-1 series cameras are legendary for their superior autofocus ability. Many
professional photographers rate Canon’s autofocus as one of the main reasons that they
use Canon equipment. The new autofocus system of the EOS-1D Mark III represents a
complete reconsideration of professional autofocus. In addition to a new sensor chip,
sophisticated new manufacturing technologies have made it possible to reconfigure the
concave submirror and the very clever secondary image formation lens. The result is
greater sensitivity, easier and more logical navigation, higher precision and significantly
better real-world performance.
In the 45-point AF system used by such cameras as the EOS-1v, 1D, 1Ds, 1D Mark II,
1Ds Mark II and 1D Mark II N, there are 7 cross-type, high-precision sensors grouped
around the center of the frame. Any of the 45 points could be selected by navigating
around the frame. This is the configuration of the previous 45-point AF array:
Previous 45-point sensor
Here is the new
AF point layout:
: Cross-type AF points
: Assist points
(Not user-selectable)
: f/2.8 sensors (Center AF point is f/4)
: f/5.6 sensors
Note that the 19 high-precision, cross-type points are no longer clustered solely in the
center of the frame. The 26 Assist AF points are horizontal-line sensitive at f/5.6, are not
user selectable, and operate not only in AI Servo AF mode, but in One-Shot AF as well
(C. Fn III-8, 1/2). The Assist AF points achieving focus light up with the super-imposed
display (SI).
The EOS-1D Mark III features higher precision AF with the 19 user-selectable, cross-type
AF points and improved lowlight AF performance. Also, to attain AI Servo AF for 10 fps,
the focus computing is faster and an AF adjustment option function is provided. The AF
sensor, AF algorithm, and AF-related electronic circuitry have been newly designed
especially for the 1D Mark III. Because of improved computing performance and faster
reading from the sensor, the AF speed, predictive AF performance, and matching accuracy
of the target subject are all the same as with the EOS-1D Mark II N despite the 10 fps
continuous shooting speed of the 1D Mark III. Of course, at 8.5 fps, the 1D Mark II N
was no slouch itself.

The 19 cross-type AF points take advantage of the following technologies:
• With finer processing steps, the peripheral circuit could be made smaller and the
f/2.8 AF sensor area could be expanded
• The secondary image-forming lens (see diagram) is glass mold. By incorporating a
newly-developed aspherical surface on the lens, the focusing area of the f/2.8 light
flux could be expanded

As with the EOS-1D Mark II N, the center AF point is a cross-type sensor. It is vertical-line
sensitive with maximum apertures as small as f/4, and horizontal-line sensitive with
maximum apertures as small as f/8. If the maximum aperture of the attached lens or
lens/extender combination is f/4 or faster, high-precision,
cross-type focusing is possible. If the maximum aperture
of the attached lens or lens/extender combination is f/8
or faster, horizontal-line sensitive AF is possible.
Compared with the other 18 cross-type AF points, the
center AF point's focusing line width is larger while the

fill factor for each pixel is larger (f/2.8 field of view).
(Not user-selectable)
: f/2.8 sensors (Center AF point is f/4)
: f/5.6 sensors
Also, the number of focusing lines increases along with
the brightness (f/5.6 field of view) to attain higher
pre-cision. Gross defocus is also detected. The camera
can also detect a grossly defocused subject 1.8 times
better than with the EOS-1D Mark II N.
The 18 cross-type AF points other than the center AF point detect vertical lines at f/2.8
and horizontal lines at f/5.6. If the maximum aperture of the lens or lens/extender
combination in use is f/2.8 or larger, high-precision, cross-type focusing is possible.
Also, if the maximum aperture of the lens or lens/extender combination in use is f/5.6
or larger, horizontal-line sensitive AF is possible.
The Assist AF sensors are horizontal-line sensitive at f/5.6.
They have the same focusing detection performance as the
EOS-1D Mark II's AF points (other than that camera’s seven
cross-type sensors). The EOS 5D's Assist AF points operate

only during AI Servo AF when the camera is set for automatic
AF point selection or the center AF point is manually selected and focusing point
expansion is activated. However, with the EOS-1D Mark III, the Assist AF points now also
operate during One-Shot AF when the camera is set for automatic AF point selection, or
when any cross-type focusing point is manually selected and focusing point expansion is
activated. The Assist AF points achieving focus also light up with the SI display. While
the high-precision, cross-type AF points have substantial coverage in the Area AF, the
center AF point can use cross-type focusing with f/4 and faster lenses and still can focus
with f/8 lenses. The AF operation certainly befits an EOS-1D series camera.
For lowlight focusing, to the EOS-1D Mark III is twice as sensitive as the EOS-1D Mark II N.
The CMOS AF sensor's pixel sensitivity has been improved, thanks to improved pixel
characteristics, an improved pixel fill factor due to finer semiconductor manufacturing
processes, and optimized pixel size. As a result, the 1D Mark III’s AF sensitivity has been
improved to EV -1 through EV 18 (at 23°C/73°F, ISO 100).
AF Unit
As with previous EOS cameras, the TTL-SIR (Through-the-Lens Secondary Image Registration)
focusing principle is employed. The light flux passes through the camera lens and passes
through the half mirror at the center of the main mirror. The light flux proceeds downward
by reflecting off the oblong, concave secondary mirror to a fully reflective mirror in the
base of the camera’s mirror chamber. Then it passes through an infrared- absorption
glass, a secondary image-forming lens, and a cover glass before reaching the AF sensor.
The AF unit uses materials having minimal swelling and moisture absorption characteristics, and the secondary image-forming lens is made of glass mold highly resistant to
changes in size due to fluctuations in temperature and humidity. The AF unit is therefore
very stable.

Also, the secondary image-forming lens is optimized for the f/5.6 and f/2.8 light flux by
having a different surface shape for the respective light flux entering the lens. The top and
bottom light flux is compatible with f/5.6, while the left and right light flux is compatible
with f/2.8. The rear side of the secondary image-forming lens features a newly-developed
aspherical surface compatible with f/2.8 lenses.
AF Start Button
The EOS-1D Mark III has a new AF Start (AF-ON) button that
can be used to execute AF and metering. We know that many
pros using the EOS-1D series cameras have set C. Fn 04-1 to
use the AE lock button for AF. The technique is called
"autofocus with your thumb" or “back button focus.”
The 1D Mark III now provides a new AF start button dedicated to AF. Pressing the AF
start button executes AF and metering. C. Fn IV-1,3 (AE lock/metering + AF start) is
equivalent to C. Fn 04-1 in previous cameras.
AF Point Selection
The AF points can be put to work in several different ways. First, the AF points can be
automatically selected by the camera from among the 45 points. Second, any one of 19
can be selected manually by the user. With C. Fn III -9-1/2, the manually-selectable AF
points can be limited to 9 inner or outer AF points (including the center AF point). The AF
point selection procedure is the same in either case. Press the AF selection button, then
turn the Quick Control Dial or Main Dial to select the desired AF point. Pressing the
Multi-Controller will select the center AF point. With the center AF point selected, pressing
the Multi-Controller will set automatic AF point selection.

As with the EOS-1D Mark II N, two separate CPU processors are used, one for AF processing
(including lens driving) and one for the camera. To attain 10 fps with AI Servo AF, the AF
CPU and camera CPU are both the latest microcomputers (AF CPU: 48 MHz, 32-bit RISC;
Camera CPU: 40 MHz, 32-bit RISC). The computing speed is 3 times faster than the
1D Mark II N's CPUs.
Predictive AF can track a subject approaching at about 31 mph
up to about 26.2 ft. away with an EF300mm f/2.8L IS USM lens.
This is the same as with the EOS-1D Mark II N. However, improvement in focusing detection performance enables subject
tracking at 10 fps.
[m ]
Subject distance
AI Servo AF
During AI Servo AF when the camera is focusing on a subject
and something closer enters the picture, the camera can either start focusing on that
closer subject or ignore it as an obstruction:
Subject's speed [Km/h]
• AI Servo AF tracking method > Main focus point priority (C. Fn III-4,0): The camera will
start focusing on the closer subject that entered the picture. When the center AF point
detects that closer subject, the focusing priority will then shift to the main AF point.
• AI Servo tracking method > Continuous AF track priority (C. Fn III-4,1): The camera will
ignore any closer subject entering the picture. The focus-tracking immediately before
the obstacle entered the picture will continue, and the AF point can shift to any other
one while tracking the original subject instead of being fixed at the main AF point.
C. Fn III-3 (AI Servo 1st/2nd image priority) is for setting the priority on focusing or on
the shutter release for the first and following shots during continuous shooting.
0: Focusing priority takes effect for the first shot as well as for the second and following
shots with focus tracking.
1: Focusing priority takes effect for the first shot, and priority on continuous shooting
speed (more than the focus tracking of the subject) takes effect for the following shots.
2: Shutter-release priority takes effect for the first shot (overriding focus). For the following
shots, priority on continuous shooting speed takes effect more than with option 1.
When "Focusing (subject-tracking) priority" is selected and the subject distance changes,
the continuous shooting speed may become irregular. When “Drive speed priority" is
selected, the focusing might be slightly off, but the shooting speed will be fixed. Setting 2
is effective for press photographers who put priority on capturing the moment.
C. Fn III -3 can be set to change operation characteristics when you press the shutter button
completely in one stroke. Settings 0 and 1 are the same as on the EOS-1D Mark II N.
When focusing is possible, the lens is driven to match the focusing result obtained
immediately before shutter release. After the lens is driven, the picture is taken. If focusing
is not possible, the picture will be taken immediately. With setting 2, the picture will be
taken immediately regardless of whether focus has been achieved or not.
During low-speed continuous shooting, the subject distance can change significantly
between shots. The slower the continuous shooting speed, the more the lens is driven
between shots to detect the subject. Thus, subject tracking is more precise. Also, with the
EOS-1D Mark III, the improved AF computing performance enables the lens to be driven
more to detect the subject than with the EOS-1D Mark II N. AI Servo AF therefore becomes
more precise. At the standard setting, the subject tracking sensitivity level is the same as
with the 1D Mark II N. Once an AF point starts tracking the subject, the tracking response
is impressive. (Subject-tracking sensitivity can be adjusted with C. Fn III –2, Slow to Fast,
-2 to +2.)
Even if AI Servo AF is used to focus on a still subject, stable control is enabled so that the
lens drive isn’t constantly fine-tuning. If the subject starts to move, the focusing responds
immediately to detect the subject constantly.
Automatic AF Point
The high detection-sensitive, cross-type AF points are now spread out over the Area AF.
When One-Shot AF is combined with automatic focusing point selection, as with the
EOS 5D and 30D, the selection of the Area AF's bottom AF points is eliminated. From among
the remaining AF points, the AF point on the closest subject is set to be the main AF point.
This is a change from the Area AF of previous EOS-1D cameras where the main AF point
was set at where the most AF points lit up. The concept of eliminating the selection of the
least reliable AF points is the same as before. With the new algorithm, AF point selection
becomes more stable and consistent even if the area of the main AF point is smaller. When
AI Servo AF is combined with automatic focusing point selection, the EOS-1D Mark III's
behavior is the same as previous EOS-1D class cameras, where the subject is initially
acquired by center focusing point and subsequently tracked by all 45 points as necessary.
AF Point Expansion
AF expansion with a manually selected focusing selected point, C. Fn III –8, differs from
the EOS-1D Mark II N's settings. Depending on the AF mode (One-Shot AF or AI Servo AF)
and focal distance, the AF point area does not change. With setting 1 (Enable left/right
assist points), the expanded area (on the left and right of the manually-selected AF point)
is enabled at all times. With setting 2 (Enable surrounding assist points), the expanded
area is enabled by one point all around the selected AF point.
C.Fn III -8-1
With One-Shot AF, when focus is achieved with an
Assist AF point, the Assist AF point will light up via the
SI display. With AI Servo AF, the manually-selected AF
point and Assist AF point will not be displayed.
C.Fn III -8-2
: Selected AF point
AF Micro-adjustment
: Expansion points
AF precision is adjusted for the camera and lens to fall within
the lens' maximum aperture's depth of focus. However, there
are users who want to adjust it more minutely. They have
had to go to a Canon Service Center to have it done.
AF micro-adjustment is a feature developed for these users.
C.Fn III-7
The user himself can now finely adjust the AF focusing
position. The adjustment range is ±20 steps in front of (-) or behind (+) the point of focus.
The adjustment increment of one step differs depending on the maximum aperture of the lens. You should
shoot, check the focus, and adjust it. Repeat this
procedure to adjust the point of focus. When a lens
registered with a point-of-focus adjustment is
attached, the point of focus will be automatically
shifted by the correction amount set.
If you set 1 (Adjust all lenses by the same amount) or
2 (Adjust by lens) and press the INFO button, the
adjustment screen will appear. The focus shift amount
per step is calculated by multiplying the maximum
aperture's single-side depth of focus by 1/8. If 1 is
set, the focus shift amount will always be the same
number of steps (but the actual amount will vary
according to maximum aperture) for all lenses. If 2
AF Microadjustment
Adjust all lenses by same amount
is set, the focus shift amount will change for each
different lens. You can register the focusing shift
amount for up to 20 lenses. Then, when you use one
of the registered lenses, the focus will shift by the
set amount.
Adjust individually for each lens
Note that since the camera does not recognize the unique ID of the lens, the same shift
amount will be applied to the same lens model even if it has a different serial number.
In the case of zoom lenses which have variable maximum apertures, the focus shift
amount is technically different at the wide-angle end and telephoto end. However, since
the focus shift amount cannot be adjusted individually for the wide and telephoto ends
(there is only one shift amount per lens), adjusting it for the telephoto end is better. If
an extender can be attached, the camera recognizes whether it is 1.4x or 2x and makes
a different shift adjustment from when no extender is attached. When an extender is
attached, the adjustment screen will display the lens name and extender name. To delete
the registered lens settings, select 1 or 2, then press the Erase button. All the registered
AF micro-adjustment settings will be cleared.
Speedlite Compatibility
When the 580EX II, 430EX, 220EX, or ST-E2 is attached to the camera, an AF-assist
beam linked to the AF point can be emitted automatically whether AF point selection is
automatic or manual. This will help the camera to focus. With other EOS-dedicated
Speedlites, the AF-assist beam might not align with the selected AF point.
Live View is a significant addition to the professional DSLR shooter’s arsenal. It is a
terrific problem-solver for all those situations in which it would be awkward, difficult or
impossible to look through the viewfinder to compose, meter and shoot. In response to
the particular requests of studio and remote sports photographers, EVF (electronic
viewfinder) shooting with a computer, wired or wireless, is now possible with the
EOS-1D Mark III. By connecting the camera via USB to a computer with the EOS Utility
2.0 software provided, the computer will display in real-time the image output by the
camera's imaging element. Then you can check and adjust the focus, subject framing
and so forth in real-time and shoot remotely. With the optional Wireless File Transmitter
WFT-E2A attached, you can use a wireless LAN and see the Remote Live View on a
computer without using a cable. Key features of Live View include a 100% field of view,
precise manual focusing with 5x and 10x magnification, the ability to previsualize
exposure, framing and focusing on a computer monitor, easy checking for moiré and false
color, displays of film-related aspect ratios, and a video-out terminal for TV display.
Camera Live View Mode
Instead of looking through the viewfinder, you can shoot while viewing the scene on the
camera's LCD monitor. This feature was mainly designed for shooting still-life subjects.
Compared to looking through the viewfinder, it provides the following advantages:
1. The real-time picture can be magnified by 5x or 10x to help make focusing more precise.
2. Shoot while checking the composition on the LCD monitor.
3. You can check the exposure on the LCD monitor before taking the picture (with
C. Fn IV -16-1 and aperture stopped down).
This is very convenient when you shoot on
a tripod or a studio stand or shoot macro
images. With [Live View shoot: Enable] set
and the camera ready to shoot, press the SET
button. The reflex mirror will then lock up,
the shutter will open, and the image output
from the CMOS sensor will be displayed in
real-time and 100% image coverage on the
camera's LCD monitor. Press the SET button
again and the reflex mirror will go back down
and the Live View shooting will end.

Remote Live View Mode is controlled through EOS Utility 2.0 (a major upgrade from
version 1.1), included on the EOS Digital Solution Disk Ver.14. The camera can be
connected either wired with the provided USB 2.0 Hi-Speed cable, or wirelessly with
the WFT-E2A. To get started, the camera must be set to Live View. Then, click the
[Starting Live View] button on the Remote Live View screen.

normal view. At 5x or 10x magnification, you can focus manually
while looking at the LCD monitor. To make it easier to focus
during the magnified view, image sharpness is applied at a
higher setting than it really is.

Live View enabled
Pressing the depth-of-field preview button stops down to the
aperture which will be used to take the picture. It will simulate
with 10x Magnification
the shooting exposure and you can check both the exposure
level and depth of field. If you use depth-of-field preview during regular viewfinder
shooting, the viewfinder will look dark and it may be difficult to see the depth of field.
However, with Live View shooting, a clever simulation is displayed so checking the depth
of field is easier as long as the exposure setting is near the metering's correct exposure.
Metering and Exposure
Evaluative metering with the imaging element is used. The metering mode cannot be
changed. The metering range is EV 0 to EV 20 (at 23°C/73°F, with EF 50mm f/1.4 USM
lens). Any shooting mode and drive mode can be used. Also, AE lock, exposure compensation, AEB, and depth-of-field preview are possible. During magnified view, AE lock is
automatically applied to the meter reading for the entire image. If C. Fn IV -16 [Live View
exposure simulation] is set to [1: Enable (simulates exposure)] and the shooting mode is
P, Tv, Av, or M, then the LCD monitor's brightness will change in response to the exposure
setting so you can see how the exposure will look before you take the picture. When you
press the shutter button completely, the opened shutter will close; the shutter will be
cocked and released, and the picture will be taken.
If flash is used, the mirror must come down briefly. Pressing the shutter button completely
will cancel the mirror lockup and the metering sensor will execute E-TTL II flash metering
control (preflash fired and the correct flash output is retained). Then the reflex mirror is
locked up again and the picture is taken. For continuous shooting, the same 10 fps
maximum shooting speed as with normal shooting can be achieved. During continuous
shooting, the LCD monitor is off. After the shooting ends, the captured image is displayed
on the LCD monitor. When the image display ends, the camera returns to the Live View
display automatically.
As with viewfinder shooting, pressing the AE lock button during Live View shooting will
lock the current exposure and an asterisk will appear on the LCD monitor. During magnified
view, AE lock will be applied automatically to the exposure level of the full view display.
The Tv and Av settings will be displayed in orange. During the magnified view, the AE lock
button will not work. With C. Fn IV -16-1, the picture brightness is also locked.
Normally, the Live View picture displayed by the LCD
monitor is always displayed at the correct brightness,
regardless of the exposure setting, for easy viewing similar
to compact digital cameras. However, if C. Fn IV -16 [Live
View exposure simulation] is set to 1, the picture is
No compensation
displayed based on the exposure setting's brightness.
This enables you to see the exposure condition before
taking the picture. The picture will be displayed at almost
the same brightness as how the actual exposure will look.
However, under low light or bright light (outside the displayable brightness range), the picture brightness might
1 1/3 stop compensation
not look the way the actual exposure will be. Exposure
simulation will not work with flash or bulb exposures.
If you press the depth-of-field preview button, exposure simulation will be active at all
times regardless of the C. Fn IV -16 setting.
Function Settings
The metering mode is set to AF point-linked evaluative
metering. Other shooting settings (shooting mode, drive
mode, image size, ISO speed, exposure compensation,
etc.) can be set in the same way as during viewfinder
shooting. The metering timer is 16 sec. (including AE
Live view function settings
lock). Focus presets with super telephoto lenses cannot
be used. Even during Live View shooting, the power will turn off after the [Auto power off]
time elapses. During Live View display, pressing the MENU or playback button will
terminate the Live View shooting and the menu screen and image playback will appear.
Info Display
Below the image, the shutter speed, aperture, exposure level (exposure compensation
amount, AEB level), flash exposure level, shots remaining, and ISO speed are displayed.
In the magnified view, the magnified location, magnification, and AE lock status are
displayed on the right of the image. In addition, when you press the INFO button, the
Picture Style, battery check, AE lock status, and flash-ready are also displayed on the
lower left of the image. If C. Fn IV -16-1 is set and you press the INFO button again, a
brightness or RGB histogram appears on the right of the image. (For flash shots and
bulb, the histogram display will be grayed out.)
Press the INFO button again and only the Live View image (without information) will be
displayed. If [Grid display: On] has been set, a four-line grid will be displayed on the image.
This can be used to check the vertical or horizontal orientation of the image. The grid
appears only in the full view mode (not in the magnified view). Also, with C. Fn IV -14
[Add aspect ratio information] set anywhere from 1 to 6, you can shoot in the same
aspect ratio as 6 x 4.5cm, 6 x 6 cm, 6 x 7cm, and 4 x 5 in., corresponding to mediumand large-format film sizes. When this feature is set, vertical lines matching the respective
aspect ratio will appear on the screen. You can then compose the subject within this
frame. Since the aspect ratio information will be appended to the image, when you open
the image with Digital Photo Professional 3.0, the image will be displayed in the aspect
ratio that was set. Note that the image areas outside the vertical lines are not actually
deleted and that when the image is played back with the camera, the vertical lines
matching the aspect ratio will also appear.

During Live View shooting, the picture is displayed and then the reflex mirror locks up
automatically to maintain Live View display (and returns later). The Live View display's
frame rate is approx. 30 fps. The picture remains smooth even if you change the camera's
direction or if the subject moves. If the camera direction is changed to a scene with a very
different light level, the Live View picture's brightness will be thrown off for a moment. If
this happens, wait until the picture brightness stabilizes again before shooting.
If the light source changes, the Live View picture may flicker. If this happens, stop the Live
View shooting and press the SET button to start the Live View shooting again. During
continuous shooting, the exposure for the first shot will also be applied to subsequent
shots. If the sun or other bright light source enters the picture, the bright area might look
dark. However, it will be correctly recorded as a bright area. Note that FE lock and
modeling flash cannot be used.

Continuous shooting)
With Live View shooting, the camera's internal temperature increases due to heat from
the CMOS sensor, and other components. For normal shooting, this is not a problem.
There is no Live View operation limit at 23°C/73°F for Remote Live View shooting and
Camera Live View shooting, whether you use a memory card or external recording media
via the WFT-E2A. However, if the camera is under direct sunlight or near hot studio lights
during Live View shooting, the camera's internal temperature will increase more than
usual and the screen may show a warning icon shaped like a thermometer. If the warning
icon appears, you can continue shooting and the operation will not be forced to terminate
if you are using a memory card. However, since the image quality might degrade, it is
recommended that you stop shooting if the warning icon appears. If you use a MicroDrive
and you keep shooting even when the warning icon appears, the Live View shooting will
terminate automatically after the internal temperature reaches a certain level. This is to
protect the MicroDrive from the heat. If the Live View shooting terminates automatically,
Live View shooting will not be possible until the internal temperature goes down.
Recording Method
With DIGIC III and improved card writing, the data writing speed is approximately 30%
faster than with the EOS-1D Mark II N.
The EOS-1D Mark II N provided three recording methods:
• Recording to only one memory card
• Recording the same image to both the CF and SD cards
• Recording the RAW image to the CF card and JPEG image to the SD card, or vice versa
The EOS-1D Mark III offers some new and highly flexible image recording options. With
the WFT-E2A wireless transmitter, USB 2.0 Hi-Speed external recording media can also
be used. Compatible devices range from popular and convenient USB thumb drives to
large-capacity hard drives as long as they can be attached via USB.
External Recording Media
With the CF card, SD card, and external media, the following recording functions can be used:
• Standard: There is no automatic switching of recording media
• Automatic switching of recording media: When the current recording medium
becomes full, the camera switches to another automatically and continues recording
without interruption
• Separate recording: A captured image can be recorded in different image sizes on
different media. Each recording medium can be set to record a specific image size
(L, M1, M2, S, RAW, sRAW) for each shot
• Recording of identical images: The same image is recorded to all recording media.
This is also possible with RAW+JPEG and sRAW+JPEG
SDHC (SD High-Capacity) is a new memory card standard (SDA Ver.2.00) established by
the SD Card Association in 2006 to handle high-capacity data from 2GB to 32GB.
Because it is compatible with SDHC, the camera can be used with SD cards having a
capacity up to 32GB.
Data Safety
when Compartment
Cover is Opened
With the EOS-1D Mark II N, if the memory card slot cover is opened inadvertently during
the writing to the card, the writing stops immediately. The writing resumes when the slot
cover is closed again. With the EOS-1D Mark III, if the slot cover is opened during the
writing operation, an alarm sounds and a warning message appears on the screen to
indicate that writing is in progress. The card writing now continues even if the slot cover
is opened. Also, if you set the power switch to <OFF> during the card writing, a message
appears on the screen to indicate that writing is in progress. After the writing is completed,
the power turns off. This works the same way as with the EOS Digital Rebel XTi/400D Digital.

Any image stored in a memory card or external media can be copied to another recording
medium (CF card, SD/SDHC card, or external media). Select the recording medium
containing the images you want to copy using the [Record funct+media/folder sel.] menu,
and individually checkmark the images to be copied. Then, select or create the folder in
the target medium to which you want to copy the images. All the images in the selected
folder can be copied to another folder which you select or create. Also, all the images in
the specified folder can be copied to the target medium with the same folder name and
same image numbering copied as well.
The images stored in the DCIM folder in the CF or SD card can be backed up to external
media via the WFT-E2A. A folder is created automatically in the external medium and is
named with a six-digit date (yyddmm) and two-digit number (00 to 99). Inside it, a DCIM
folder is created to which all the images are saved. Either select a target folder in the
external medium or create a new folder with an eight-character name. Inside it, the images
will be saved to the DCIM folder.
When creating or selecting a folder, the screen now shows
the image of the lowest and highest image file number on
the right.
Creating and selecting a folder
In addition to the [Preset code] and [User setting1] each having 4 characters, [User setting
2] with 3 characters + 1 Image size character is newly provided. When [User setting 2] is
set, the image size that has been set for shooting is appended automatically to the file
name as the fourth character from the left (ex: xxxx0001.JPG). You can thereby know the
image size by seeing the file name instead of having to open the image file. The appended
characters are L for Large/RAW, M for Medium1, N for Medium2, and S for sRAW. RAW
and JPEG can be distinguished with the extension.

Improved Body Design and
The EOS-1D Mark III retains and refines the beautiful curved surfaces and superb basic
layout of the EOS-1 series. Ease of operation and holding comfort have been improved
appreciably, as has ease of operation with accessories. The new camera is designed to
be easier to understand and more reassuring. The massive strength of its magnesium
alloy body and chassis, combined with complete environmental sealing, means that the
1D Mark III stands with its forebears as an instrument worthy of the photographers who
risk their lives daily to take pictures.
Most of the major body components are arranged in the same way as with the EOS-1D
Mark II N. The following major units are new or different:
• Self Cleaning Sensor Unit
• LCD monitor now 3.0 inches (was 2.5 inches)
• To attain 10 fps, two drive motors are incorporated
• Extension system terminal is provided for the WFT-E2A Wireless File Transmitter
Lower cost has been achieved with a less costly imaging element developed and manufactured by Canon and by downsizing electronic circuits with smaller boards and higher
circuit integration resulting in fewer parts.

Dimensions and Weight
Mechanical Components
The dimensions of the EOS-1D Mark III are (W x H x D): 156 x 156.6 x 79.9 mm/6.1 x 6.2
x 3.1 inches. The weight is 1155 g/40.7 oz. (body only, no battery, no memory cards),
1335 g/47.1 oz. (with battery). Compared to the EOS-1D Mark II N, the height is 1 mm
shorter; the body-only weight is a significant 70 g/2.5 oz. lighter, and the weight with
battery is a remarkable 225 g/7.9 oz. lighter. The LP-E4 battery of the EOS-1D Mark III
weighs 180 g/6.3 oz.; the NP-E3

EOS-1D Mark II N
Because of its lightweight and strength, magnesium alloy is
used for the top, front, and rear covers as well as for the
memory card slot covers. The chassis and mirror
box are also made of magnesium alloy (instead
of the EOS-1D Mark II N's aluminum die cast) to
make the body very strong, rigid, and light.
The magnesium alloy also works as an electromagnetic shield. Except for its deeper black
color, the paint finish on the exterior covers is
the same as the 1D Mark II N's. It is highly
durable, allowing minimal wear even under
harsh conditions.
To equal the legendarily excellent water- and dust-resistant construction of the
EOS-1D Mark II N, measures are incorporated at 76 places around the camera controls
and along cover seams. Also, O-rings are used on the memory card slot covers and the
battery compartment, and silicon rubber is employed around the top and rear covers and
buttons where the user can see it and feel reassured. The EOS-1D Mark III's hot shoe is
shaped to resist water with a rib around its perimeter. When the Speedlite 580EX II is
attached, water resistance is maintained. When a water-resistant EF lens is attached to
the camera, the entire camera-and-lens outfit will be water-resistant.
Location of major water-resistant measures

While based on the EOS-1D Mark II N's shutter unit,
the EOS-1D Mark III's shutter unit has been improved to
increase durability and to reduce the generation of dust.
It is now rated for 300,000 shutter cycles. (The
1D Mark II N’s shutter unit durability rating is 200,000
cycles.) To attain this level of ruggedness, surface finish

and heating processes in manufacturing have been
changed for specific highly durable parts. To increase stability and shutter precision, a
photo reflector (PR) is newly employed to detect the slit-passing time. For the X-sync
contact, the mechanical contact has been eliminated to prevent contact scorching and
wear. By employing PR signals for the

self-timer and 2-sec. self-timer. During normal shooting, a magnet is used to release the
tension and the reflex mirror's downward motion is spring-driven. In the silent single
shooting mode, Pulse Width Modulation (PWM) control is employed to lower the effective
voltage. The motor's rpm is lowered and the reflex mirror is slowly put back down. PWM
control is also applied to the shutter-cocking motor to make it silent. The operation noise
of the mirror going back down is approx. 77 dB for normal single shooting. In the silent
single shooting mode, it is much quieter at approx. 70 dB. After shooting in the silent
single shooting mode and SW2-OFF occurs, the shutter will be cocked. You can thereby
control the timing of the operation noise.
A top continuous shooting speed of 10 fps is attained in both the One-Shot AF and AI Servo
AF modes even though the EOS-1D Mark III has about 1.23 times more pixels than the
EOS-1D Mark II N. This was made possible by the new drive mechanism (a new bound/
bounce prevention mechanism for the reflex mirror's downward motion, a dedicated
motor for mirror cocking, and a dedicated motor for shutter cocking), a CMOS sensor
enabling 8-channel high-speed signal reading, a newly-developed shutter unit, and

the same as well. However, to make
vertical shooting feel the same as horizontal shooting, the vertical grip's shutterrelease stroke and torque have been altered. They are now almost the same as with
horizontal shooting. Also, to make the camera operation feel the same as that of the
1D Mark II N, the shutter-release time lag from SW-1 ON is 55 ms (up to 3 stops from
the maximum aperture). The viewfinder blackout time is 80 ms (87 ms with the 1D
Mark II N). The shutter-release time lag at maximum aperture can be shortened to
approx. 40 ms with C. Fn IV-13 [Shortened release time lag].
Metering and Exposure
The EOS-1D Mark III incorporates a newly-developed, 63-zone
metering sensor linked to the 19 AF points. The metering sensor
is located at the rear of the pentaprism. The 19 AF points in the
Area AF are a highly favorable match for the metering sensor’s
zones. The metering range is EV 0 to EV 20 (at 23°C/73°F, EF
50mm f/1.4 USM lens, ISO 100).
The new evaluative metering algorithm is based on the algorithm for the previous 21-zone
and 35-zone metering systems. With the optimized 63-zone metering sensor and
improved algorithm, more consistent and correct ambient and flash exposures are
obtained with less influence by the subject. The basic concepts for the evaluative
metering algorithm are:
1. Metering is weighted on the linked AF point.
2. If there is a very bright object in the picture, the exposure will be increased.
3. In backlit scenes, the exposure will be increased. With dark backgrounds,
the exposure will be reduced.
The E-TTL II autoflash algorithm uses the newly-developed 63-zone metering sensor.
While based on the previous algorithm which weighted the metering based on the
preflash reading, this algorithm has been further improved to obtain consistent flash
exposures. The major improvements are:
1. Correct flash exposures are obtained even with off-center subjects.
2. The incorporation of lens distance information has been optimized to obtain more
accurate flash exposures even with highly reflective backgrounds.
The following metering modes are provided: evaluative, partial, spot, and center-weighted
average (the same as the EOS-1D Mark II N). Also, multiple spot metering and AF pointlinked spot metering is possible with C. Fn I -7-1. Partial metering reads approximately
13.5% of the viewfinder and spot metering reads approximately 3.8%. The ISO bracketing
feature has been eliminated because a survey has shown it to be used very infrequently.
average metering
Partial metering
Spot metering
* C.Fn I -7-1 enables AF point-linked spot metering.
The following shooting modes are provided: P, Tv, Av, M, and Bulb (the same as the
EOS-1D Mark II N). A convenient and helpful ISO speed safety shift is provided via C.Fn
I -8-2. If the correct exposure cannot be obtained with the P, Tv, or Av mode, the ISO
speed is automatically shifted within ISO 100 - 3200 to obtain the correct exposure.
Safety Shift
Safety Shift is a practical feature that is enabled/disabled through C.Fn I-8. 0 disables
the function. 1 enables either a shutter or an aperture preferred shift and 2 enables an
ISO shift. The function makes it less likely that a busy shooter will get caught out as
conditions change rapidly.
The USB 2.0 Hi-Speed is now incorporated, replacing IEEE 1394/Firewire. Thanks to the
higher efficiency of the internal interface with DIGIC III, data transfer speed is much
faster than with the EOS-1D Mark II N. Since the USB speed also greatly depends on the
personal computer hardware environment, the transfer speed might not be about 2.5
times as fast in all user environments. The USB interface cable is about 6.6 ft./2m long
with both ends having a ferrite core-equipped A: Mini B connector. It can be used to
connect the camera to a personal computer, printer, external media (via WFT-E2A), or
GPS. An optional 16.4 ft./5m cable has also been developed.
A cable protector for the EOS-1D Mark III has also
been developed to prevent deformation or damage
of the terminal due to excessive strain on the
terminal, to reduce wear, and to prevent the USB
cable from being disconnected accidentally. The
cable protector is designed to be usable even while
the WFT-E2A is attached to the camera.
Cable protector
A 15-pin extension system terminal is provided for
connection to the Wireless File Transmitter WFT-E2A.
Because this terminal is located behind the USB and
other connections, the other terminals can still be used
even while the WFT-E2A is attached. Terminals other
than these are the same as with the EOS-1D Mark II N:
PC terminal, video out terminal (NTSC/PAL), and
remote control terminal (N3 type).
The EOS-1D Mark III's power source system has been
changed from the old EOS-1D power source system. The
new, dedicated, high-performance, lithium-ion Battery
Pack LP-E4 (3 cells, 11.1V, 2300 mAh) is compact and
lightweight, taking full advantage of current lithium-ion

technology. Compared to the NP-E3, it is much smaller
(40% less volume) and lighter (46% lighter). It can also communicate the following
information with the camera: Power source type, remaining capacity 6-level icon, display
in 1% increments, shutter count, and recharge performance (3 levels). This information
can be viewed with the [Battery info.] menu. The new system also
consists of Battery Charger LC-E4 and AC Adapter Kit ACK-E4.
Battery Pack LP-E4
Battery Check
An IC chip in the battery tracks battery information. Battery level is
displayed upon communication with the chip. The remaining battery
level is indicated by a battery icon indicating one of six levels on the
top LCD panel, in the viewfinder (during metering), and on the menu
screen [Battery info.]. If communication with the battery chip fails, a
communication error message will appear. By selecting [OK], you can
continue shooting. (The battery icon will be displayed as empty.)
Level (%)
100 – 70

The [Battery info.] screen shows battery-related information:
• Power source: The battery type is communicated and displayed
• Remaining capacity: When Battery Pack LP-E4 is used, the
battery icon indicates the remaining capacity in one of six
levels and in 1% increments (Under very low temperatures, Battery Info.
using the WFT-E2A + external media, if the current capacity indicates 10%, the display
may suddenly change to 0%)
• Shutter count: After the LP-E4 is fully charged, the number of shots taken with that
battery will be displayed. This number is retained even when the battery is removed.
The number will be reset when the battery is recharged
• Recharge performance: Upon communication with the battery, the battery's recharge
performance is displayed in one of three levels. A degraded/older battery will have a
lower capacity that can be recharged. Fewer shots can be taken with that battery than
with a new battery. When a degraded/older battery is fully charged, the remaining
capacity will still indicate 100%
After the battery undergoes 20 discharging and charging
cycles, a message recommending battery calibration will
appear on the bottom of the screen the next time the
battery is installed. Calibration is performed with
Battery Charger LC-E4 to find out the battery’s capacity
so that the remaining battery level can be indicated
accurately. Each time the battery is recharged and used or
Battery Charger LC-E4
discharged naturally, a slight discrepancy between the
battery's remaining capacity information and the actual remaining capacity develops.
With repeated recharge/discharge cycles, this discrepancy can become a large one. By
performing calibration to discharge the entire battery and by recharging the battery fully,
accurate battery capacity information can be obtained. Two battery packs can be
attached to the LC-E4. It takes about 120 min. to recharge one battery pack. The charger
is compatible with DC power (12V/24V) so you can connect it to a car battery with Car
Battery Cable CB-570 to recharge the battery pack.
Thanks to the newly-developed, large-capacity (2300 mAh), lithium-ion battery pack,
the new DIGIC III imaging engine, revised circuits, the new LCD monitor with low power
consumption, and fine power control, the number of possible shots is approximately
2200 at 23°C/73°F and 1700 at 0°C/ 32°F. (The EOS-1D Mark II N: 1200 shots at 23°C/
73°F or 800 shots at 0°C/32°F)
For the date/time (backup) battery, the same CR2025 lithium battery as the
EOS-1D Mark II N is used. The battery life is 5 years.
The AC Adapter Kit ACK-E4 supplies household AC power to the EOS-1D Mark III. It consists
of the AC adapter, power cord, and DC coupler. The DC coupler has a DC cord. The plug
at the end of the DC cord connects to the AC adapter's
terminal; it prevents accidental disconnection.
The previous AC Adapter Kit had the DC cord and AC
adapter as one unit, and the plug was connected to
the DC coupler.
AC Adapter Kit ACK-E4
Ease of Operation
In order to provide ease of operation that befits a new-generation EOS-1D series camera,
Canon has thoroughly investigated ways to make camera operation easier. The camera
retains the EOS Digital line's basic operation method with the Main Dial, Quick Control
Dial, Multi-Controller, SET button, and other buttons to select and set various functions.
Also, the ISO speed button, AF Start (AF-ON) button, Picture Style button, and Memory
selection/Image size/White balance function button have been newly added to make
camera operation easier.
With the older EOS-1D series cameras, the basic shooting operation logic consisted of
holding down a button and turning the Main Dial or Quick Control Dial to select a setting.
However, with the EOS-1D Mark III, when you press a button, it remains active for a while
so you can let it go and then turn a dial to set something. Also, the three buttons on the
top left of the camera accept double pressing. You can therefore set something (except
AEB) with just one button.
With the EOS 5D and 30D, the Multi-Controller serves as the AF point selector. However,
with the EOS-1D Mark III, we concluded that it was best to use the Quick Control Dial or
Main Dial to select one of the 19 AF points. The Multi-Controller serves as a supplemental
camera control for the digital operation's UI. If you press the AF point selection button
and then press the Multi-Controller, the center AF point/automatic AF point selection can
be made. Any other AF point (other than center AF point) cannot be selected.

With the battery check detection system, the battery check indicator now shows 6 levels
instead of 4. This gives you a more precise indication of battery level. Since the Personal
Functions have been consolidated with the Custom Functions, the # (P. Fn) icon has
been discontinued.
The image size indicator for the external media and respective recording media and

The large 3.0-in. TFT monitor (1.4 times larger in area than 2.5 inches) features approximately 230,000 pixels, a wide-viewing angle (140° both vertically and horizontally),
high-level brightness, and low power consumption. The LCD monitor is backlit with
four LED modules. The maximum brightness is about 1.8 times brighter than the
EOS-1D Mark II N's LCD monitor, making it easier to see the image on the LCD monitor
even in bright outdoor conditions. The brightness adjustment has therefore been
increased to seven levels (from five) to make the camera more adaptable to environmental
conditions. A large, clear grey scale is
provided for guidance. Also, the color
reproduction range has been increased
and gamma is added to simulate a
personal computer monitor. Thus, color
reproduction is improved to make the
images look more natural.

The viewfinder design is entirely new and is now easier to see, clearer, and sharper. The
viewfinder has approximately 100% coverage, 0.76x magnification, a 30° angle of view,
a 20mm eyepoint, -3 to 1 dpt. dioptric adjustment, and an eyepiece shutter which is now
gray to make it easier to see when it is closed. By comparison, the EOS-1D Mark II N has
approximately 0.72x magnification and a 28.2° angle of view.

The viewfinder’s optics have been developed to achieve best-in-class performance. The
same highly refractive material found in the EOS-1D Mark II N is used for the pentaprism of
the EOS-1D Mark III. To improve viewfinder magnification, a larger pentaprism is employed.
The basic configuration of the eyepiece optics is the same as with the 1D Mark II N, with
4 lens elements. However, by increasing lens power, high magnification is attained. To
improve lens sensitivity for higher magnification, the mechanical parts configuration is
of higher precision.

The Ec-C IV focusing screen is a Laser Matte unit whose molding method has been
improved over the previous Ec-C III focusing screen's. It makes it easier to focus and
provides natural-looking background blur (bokeh). It is also brighter and less grainy,
making it a very well-balanced focusing screen. With the improved molding method,
image transfer is better. The dispersion characteristic is improved, and the screen is
brighter with minimal flare. The fresnel lens area is especially improved for image transfer, increasing the peripheral brightness and making the screen look clearer overall.
Compared to the EOS-1D Mark II N's
Ec-C III standard focusing screen, the
Ec-C IV is brighter, less grainy, and
better balanced. The EOS-1D Mark III
is compatible with all Ec focusing screens used by EOS-1 series cameras.
Since the eyepiece frame now has a different shape to accommodate the bigger eyepiece lens, viewfinder accessories dedicated
to the EOS-1D Mark III have been developed at the same time:
Eyecup Eg, Dioptric Adjustment Lenses Eg (7 types: -4, -3, -2, 0,
Eyecup Eg
+1, +2, +3), and Anti-fog Eyepiece Eg. Note that the old EOS-1
viewfinder accessories Eyecup Ec-II, Rubber Frame Ec, and Anti-fog Eyepiece Ec are not
interchangeable with the Eg-series accessories. The newly-developed, standard Eyecup
Eg has an improved mount for attaching it to the eyepiece. It is now less prone to detach
inadvertently compared to the old eyecup.
Menu Functions
The Main Dial is used to select the menu tab; the Quick Control Dial is used to select the
menu option (each tabbed menu does not require vertical scrolling). Then, the SET button
is pressed to register the setting. This ease of operation is new. (With the EOS 5D and 30D,
the Quick Control Dial is used to scroll. With the EOS Digital Rebel XTi/400D Digital, the
Cross keys are used to select the tab and menu option. This operation method makes it
quick and easy to find and set the menu option from among the many menus organized
under nine tabs (Shooting 1 & 2, Playback 1 & 2, Set-up 1, 2, & 3, Custom Functions,
and My Menu). All the menu items are visible on one screen. Also, the tab design has
been changed to make it easier to distinguish; it also becomes bigger when selected.
With the Multi-Controller, only the menu tab and first layer of menu options can be selected.
Pressing the center does not set anything. It also does not work with the second layer
of menu options and beyond.
On one screen, up to 7 menu options can be displayed. This is one fewer than the 8 items
the EOS-1D Mark II N's screen can show. However, together with the bigger 3.0-inch screen,
the EOS-1D Mark III's menus are easier to read.
Playback and Display
There are four display options:
1. Single image
2. Single image + Image size
3. Shooting information
4. Histogram (1. Brightness, 2. RGB)
Each time you press the INFO button, the display changes in this sequence. With the
EOS-1D Mark III, display options 2 and 4 are new. You can also set the display for
highlight warning (highlight areas with no image will blink) and AF point.

White Balance
The white balance and color temperature settings are the same as those on the EOS-1D
Mark II N. Now white balance can be set with the menu in addition to setting it while
looking at the rear LCD panel. The lowest color temperature has been extended by 300°K,
and the settable range has been expanded to 2500°K–10000°K in 100°K increments.
The Custom white balance can now be registered with up to 5 images shot on the spot,
in addition to registering it with an image in the memory card. The registered Custom WB
data can also be captioned. Up to 5 Personal white balance settings can be registered
(PC1–PC5). On the EOS-1D Mark II N, 3 settings could be registered.
The Custom white balance function has been
improved. It is still set with the [Custom WB
regist.] menu and, as with previous cameras,
you can select an image stored in the memory
card and obtain and register the custom WB data.
Now, you can also take a picture and register
the custom WB data. Up to 5 custom WB data
items can be registered, a useful upgrade.

C. Fn I-3 is an expanded version of the EOS-1D Mark II N's
[ISO expansion]. By selecting [Register], the upper limit can
be set to H (ISO 6400) and the lower limit can be set to L
(ISO 50). If both H and L are set, it will be the same as the
previous camera's [ISO expansion: On].
C.Fn I-3
The EOS-1D Mark II N's C. Fn-09, [Auto bracketing sequence/
cancel], has been split into C. Fn I -4 and 5, [Bracketing
sequence]. Both functions can now be set separately.
C.Fn I-4
•[0: On]
The AEB and WB-BKT setting will be canceled when the power switch is set to <OFF> or if
the camera settings are cleared. AEB will also be canceled if Bulb is set or if the flash is
ready. With the EOS-1D Mark III, the bracketing will not be canceled even if the lens is
changed, the card slot is opened, or the battery is removed.
•[1: Off]
Even if the power switch is set to <OFF>, AEB and WB-BKT setting will not be canceled. When
the flash is ready, AEB will be canceled. However, the AEB level will be retained in memory.
C. Fn I –8 [Safety shift], is an expanded version of the
EOS-1D Mark II N's C. Fn-16 [Safety shift in Av or Tv]. The
function [2: Enable (ISO speed)] works in the P, Tv, and Av
modes. If subject brightness changes erratically and the
correct autoexposure cannot be obtained, the ISO speed
C.Fn I-8
is shifted automatically within ISO 100–3200 to obtain a
correct exposure. Safety shift overrides the following settings: C. Fn I -3 [Set ISO speed
range], C. Fn I -12 [Set shutter speed range], and C. Fn I -13 [Set aperture value range].
During continuous shooting, safety shift might be applied even if flash is used. It depends
on the shooting conditions.
If C. Fn II –3, [Highlight tone priority], is on, safety shift will be applied within ISO 200 3200. Safety shift to the ISO speed expanded range (L and H) will not occur. However,
shifting from L or H to ISO 100–3200 can occur. Even if C. Fn I -2 [ISO speed setting
increments] is set to 1 stop, the safety shift will occur in 1/3-stop increments.
The basic function of C. Fn I –14, [Apply shooting/metering
mode], is the same as P. Fn-06 [Registers and switches the
shooting mode and metering mode]. While you hold down
the AE lock button during shooting, the registered setting
(shooting mode, metering mode, shutter speed, aperture,
C.Fn I-14
or exposure compensation) is applied. With the
EOS-1D Mark III, you can set the AE lock button to execute AF. Unlike the EOS-1D Mark II N,
you need not press any button to register the setting. Everything can be done with the
menu screen. Since the 1D Mark III does not have an Assist button, press the AE button
to apply the registered setting.
C. Fn II –9, [INFO button when shooting] is a new function.
When [0: Displays camera settings] is set, you can now press
the INFO button to display the camera settings while the
camera is ready to shoot. This is similar to the EOS 5D and
30D. Note that if [1: Displays shooting functions] is set,
shooting-related settings as shown on the top LCD panel and C.Fn II-9
in the viewfinder will be displayed. As with the EOS Digital Rebel XTi/400D Digital, you
can then set the shooting functions while looking at the LCD monitor. This is convenient
when it is difficult to view the top LCD panel while shooting,
such as when the camera is pointed straight down. Also, while
the shooting functions are displayed, you can press the AF point
selection button to select an AF point on the LCD monitor.
Shooting function display
C. Fn III –6, [Lens AF stop button function], is the same
function as the EOS-1D Mark II N's C. Fn-19 except for the
addition of [6: AF point history selection]. When 6 is set,
you can switch between the current AF point and the
previously-selected AF point by holding down the lens AF
Stop button and pressing the FE lock button.
C.Fn III-6
C. Fn III –10, [AF point auto selection], consolidates the
EOS-1D Mark II N's C.Fn-11-2 and P.Fn-17/18 to suit the
EOS-1D Mark III's AF point selection specifications. For AF
point selection, you can enable or disable automatic selection.
The setting before the slash is the Quick Control Dial
C.Fn III-10
operation while metering is active with C. Fn IV 3-1 set. The
setting after the slash is Main Dial's operation when the AF selection button is pressed.
C. Fn IV –6, [Dial direction during Tv/Av], is a new function,
similar to P. Fn-27. When [1: Reverse direction] is set, turning
the dial to set the shutter speed or aperture will work in the
reverse direction. In the manual exposure mode, the setting
direction of the Main Dial and Quick Control Dial will be
C.Fn IV-6
reversed. In other shooting modes, the Main Dial's setting
direction will be reversed. This will make the Quick Control Dial's setting direction the same
for both the manual exposure mode and exposure compensation setting. With previous
EOS-1D cameras, even with P. Fn-27, the Quick Control Dial's setting direction could not
be made the same for the manual exposure mode and exposure compensation setting.
C. Fn IV –8, [WB + media/image size setting], is a new
function. When the camera is ready to shoot and you press
the Function button, you can choose to set the white balance,
memory card, and image size with the rear LCD panel or with
the menu screen. With [1: LCD monitor], each time you press
the Function button, the menu screen will change for setting C.Fn IV-8
the white balance, image size, recording function, and media folder setting.
C. Fn IV –10, [Button function when Quick Control Dial <OFF>],
is an expanded version of P. Fn-30. When [1: Disable Main
Dial/Quick Control Dial, Multi- controller] is set and the power
switch is set to ON, the Main Dial, Quick Control Dial and
Multi-Controller will not be able to change any settings. This
prevents accidental changing of the settings. The function is C.Fn IV-10
very convenient and eliminates a source of anxiety for many photographers who shoot
in chaotic conditions.
Saving and Registering
Registering Custom Function settings works the same way
as the EOS-1D Mark II N's P. Fn-00. With [C. Fn setting register/
apply], you can register up to three sets of Custom Function
settings in the camera. You can use each set suiting a specific
genre of shooting such as sports, landscapes and so forth.
C.Fn setting register/apply
When you apply a set of Custom Function settings, the
camera's Custom Function settings will change instantly accordingly. Note that C. Fn III -7
[AF Micro-adjustment] and C. Fn IV -11 [Focusing Screen] settings will not be included in
the registered Custom Function settings.
[Save camera settings to media] is an expanded version of
the EOS-1D Mark II N's [Save camera settings] function. Up
to 10 sets of camera settings can now be saved to one
recording medium. With [Save/ load setting on media], the
camera's current settings can be saved as a file to a memory
Save camera settings
card. When this file is read, the camera will be set to the
file's saved camera settings. The same file can be read by multiple EOS-1D Mark III
cameras or you can use different camera settings for different shooting situations. The
date/time, language, video output format settings, C. Fn III-7 and C. Fn IV-11 are not
saved and included.
[Register basic camera settings] is an expanded version of P.
Fn-25, [Sets the default settings when the CLEAR button is
ON]. With [Regist/load basic settings], you can register basic
settings such as the shooting mode, metering mode, and
drive mode in the camera. When these settings are applied,
Register basic camera settings
the camera settings will switch to the registered settings.
This is convenient when you often have to switch camera settings instantly to suit a
particular shooting situation. The following settings can be registered: Shooting mode,
white balance, drive mode, metering mode, AF mode, AF point, color space, image size,
and Picture Style (9 settings).
My Menu
Up to six frequently-used menu options and Custom Functions
can be registered in the user-friendly feature, My Menu. The
menu's top-level options, the Custom Function's top-level
settings, and all Custom Functions can be registered. You
can change the order of the menu items, delete menu items,
or delete all the menu items. Also, if [Display from My Menu:
Display] is set, pressing the Menu button will display the My
Menu (tab) first. EOS Utility can also be used to set My Menu
and register it in the camera.
My menu settings
My menu (example)
Picture Style
The Picture Style and their respective effects are the same as with the EOS-1D Mark II N.
The back of the camera has the new Picture Style button that also functions as the
Protect/Sound recording button. When the camera is ready to shoot, you can press this
button to display the Picture Style screen as a short cut. The Picture Style menu screen
also shows an icon in front of each Picture Style.
Camera Direct Functions
To improve the camera's operation with Canon printers, Canon has made four
improvements to PictBridge: faster printing speed, printing layout, printing effects, and
cable disconnection after data transfer completion. The EOS-1D Mark III supports all of the
above as well as RAW and sRAW image printing via PictBridge. Any Canon or non-Canon
old or new PictBridge printer can be used to print images. RAW images not taken with
the 1D Mark III cannot be printed from the 1D Mark III to a PictBridge printer. With
RAW/sRAW + JPEG images, the JPEG image is printed.
The [Red-Eye 1] printing effect has been added to: [Off], [On], [Vivid], [NR], [Vivid+NR],
and [Face brightener]. When [Red-Eye 1] is used for a flash shot containing red eye, the
red eye can be corrected before printing.
Due to the high-end features now available with PictBridge and the widespread sales of
PictBridge printers by Canon and other makers, the EOS-1D Mark III does not support
Canon's BubbleJet Direct and CP Direct. It supports only PictBridge. If the iP6700D for the
Japanese market or the PIXMA iP6320D, iP6310D, or iP6700D for the overseas market is
connected to the camera, the feature extension screen cannot be displayed (therefore
[Red-eye corr.] cannot be selected). Therefore, [Red-Eye 1] is newly provided as an optional
printing effect. If the connected printer has Red-eye Correction and Facial Brightness
Correction, the feature extension screen's [Red-eye corr.] can be used. ([Red-eye 1] will not
appear as an optional printing effect. Because the EOS-1D Mark III is not compatible with
Canon's BubbleJet Direct and CP Direct, when the CP500, CP400, CP330, CP300, CP220 or
CP200 is used, PictBridge takes effect and the printer's full potential can be used. (The
CP500, CP400, CP330, CP300, CP220 and CP200 provide both CP Direct and PictBridge
and ordinarily give priority to CP Direct.) Also, with the CP730, CP720, CP710, CP510, an
improved communication algorithm has improved the printing speed.
The [By Folder] button has been added. You can now select
the folder whose images (all of them) are to be printed.
Alternately, you can just cancel the printing. Other features
are the same as those of the EOS-1D Mark II N.
Print order
By using the camera controls, you can transfer JPEG, RAW or
sRAW images directly to a Mac or Windows computer with the
EOS Digital Solution Disk Ver.14 installed. The options are:
(1) All images: All images stored in the memory card are
transferred to the PC.
Direct transfer
(2) All images not yet transferred: Only images that haven't
been transferred to the computer are automatically selected for transfer.
(3) Images marked for transfer: Select images individually [Sel. image] or select all
images [All image] to be transferred to the personal computer: Up to 998 images can
be selected for the transfer.
(4) Select and transfer: Select the images to be transferred and they will be transferred
one by one.
(5) Personal computer wallpaper: Select the image to be the personal computer's
wallpaper, then transfer it (JPEG only).

Dedicated Wireless File
Transmitter WFT-E2A
The Wireless File Transmitter WFT-E2A is a speedier, handier and more flexible evolution
of the WFT-E1A. Three communication modes are available: FTP, PTP and HTTP.
(Transmission of select images is now possible with the SET button.) It supports IEEE
802.11 b/g and 100 BASE-TX LANs, both wired and wireless. Image transmission is faster
than with the previous unit. Its dust- and water- resistance performance is about the same,
despite the addition of an extra port. Wireless transmission incorporates a security function.
The WFT-E2A is equipped with a USB 2.0 Hi-Speed host interface so that it can be
connected to an external medium (such as a USB flash drive, a self-powered portable HDD
or a photo storage device) to store images, or, very usefully, to a GPS receiver (including
some Garmin and Magellan products—details to be advised).
The new unit is dedicated to the EOS-1D Mark III and gets its power from the camera and
the antenna is embedded. The result is a decrease in weight from 165g to 75g and a
similar decrease in size. There is an improved connection wizard and the WFT-E2A
features easier setting than WFT-E1A.
Because it is a wireless LAN apparatus, the same as the WFT-E1A, the WFT-E2A can be
used only in the countries and regions where Canon has acquired relevant licenses.
Photographers must obey local regulations where the equipment is used, not purchased.
For example, for outdoor use, the unit is prohibited in France and an approval is required
in Italy and Latvia.
WFT-E2, 13 channels available in the following countries: Japan, France, Italy, Germany, UK,
Netherlands, Spain, Belgium, Luxemburg, Ireland, Denmark, Greece, Portugal, Austria,
Finland, Sweden, Poland, Hungary, Czech, Slovakia, Slovenia, Estonia, Latvia, Lithuania,
Cyprus, Malta, Iceland, Norway, Switzerland, Australia, New Zealand, China and Singapore
WFT-E2A, 11 channels available in the USA and Canada, in addition to the countries
listed above.
Original Data Security Kit
Original Data Security Kit OSK-E3 is an optional accessory with the same original data
verification features as the DVK-E2 plus new functions that expand its usefulness. With
the EOS-1D Mark III, GPS data can be added to the metadata.
Image data encryption/decryption (secured transmission) is also possible with the
EOS-1D Mark III. Designed for press applications, this feature will prevent the wrongful
use of images intercepted at public events. With the OSK-E3, the images themselves are
encrypted. Encryption of images requires the use of a registered camera and the Original
Data Security (OS) card. Decrypting image files on the OS card and viewing or saving them
requires user authentication.
The kit consists of the Original Data Security (OS) card, the USB reader/writer, and the
dedicated application programs (in the EOS Digital Solution Disk). The OSK-E3 can be used
with images taken by the EOS-1D Mark III, EOS-1Ds Mark II, 1Ds, 1D Mark II N, 1D Mark II,
5D, 30D, 20D, and 20Da. The encryption feature can be used only with the EOS-1D Mark III.
Canon EF 16–35mm
f/2.8L II USM Lens
The Canon EF 16–35mm f/2.8L USM is a wide-angle zoom lens covering focal lengths
from 16mm upwards that has enjoyed strong support from many professional and highend amateur users. Many photographers renowned for the technical and aesthetic
excellence of their work name this lens as their favorite, the one they would take on a job
or journey if they could have just one lens. Some photographers carry two of them on an
extended project because it is the one lens they cannot afford to lose. At the same time,
there has been strong demand from the market for an improvement in the peripheral
image quality in wide-angle shots. In response to this demand, Canon has developed
the EF 16–35mm f/2.8L II USM as the successor to the EF16–35mm f/2.8L USM. This is
a high-performance L-series lens, specifically designed for improved peripheral image
quality in wide-angle shots that will meet the strict requirements of professional and
high-end amateur users more successfully than its predecessor.
Its features include:
• L-type wide-angle zoom lens covering the ultra-wide-angle 16–35mm range
• 3 high-precision aspherical lens elements, each of a different type: ground in G1, replica
in G2, and GMo in G16, 16 elements in 12 groups, total, giving it even better image
quality than its predecessor
• 2 UD lens elements (G12 and G15) minimize lateral chromatic aberration (a wide angle
lens design problem) to produce superb image quality with excellent resolution and
contrast and little or no color bleed around the outline of the subject
• Lens disposition and coatings optimized to minimize the ghosting and flare that tend
to occur when the lens is used with a digital camera
• High resistance to dust and water droplets
• Circular aperture produces beautiful out-of-focus images
• Internal focusing (some elements of the second group, G5 to G7, move for focusing),
ring USM, high-speed CPU and new AF algorithms for fast and quiet autofocusing
• Front element does not rotate during focusing and zooming (convenient with polarizer use)
• Manual focusing enabled even during the AF mode (full-time mechanical manual focus)
• Optical system constructed using only lead-free glass
• Uses new EW-88 petal-shaped lens hood
• Slightly larger than previous lens: filter diameter 82mm, was 77mm; length 111.6mm,
was 103mm; weight 635g, was 600g
Canon EOS System
The EOS-1D Mark III is compatible with virtually all of the vast Canon EOS System with the
exception of EF-S lenses that are designed for smaller sensors. As a practical matter, this
means an endless array of new and older equipment is available to buy throughout the
world, to rent as necessary, and to borrow from in-house pools. A Canon photographer
can always upgrade, downsize, augment or back up as requirements dictate.

Operating Conditions
All the specifications above are based on Canon's testing standards. The camera's specifications and physical
appearance are subject to change without notice.
The EOS-1D Mark III is the ultimate instrument for high pressure, high-speed photography,
and it can do much, much more. It has the image quality, the ease of control, the speed
and the flexibility to adapt brilliantly to just about any condition. Features such as the new
integrated cleaning system make it easier to live with. With Live View, the possibilities
are limited only by the imagination. The Dual DIGIC III Image Processors give it dazzling
speed and the 14-bit output will help to make superb prints and magnificent magazine
spreads. The battery data is a source of reassurance. Additions such as safety shift, highlight tone priority and high ISO noise reduction make stress-free success a given.
The retail price of the EOS-1D Mark III at introduction will be very similar to the price at
which the EOS-1D Mark II N debuted. Considering all the improvements and meaningful
new functions, the new camera is a stunning deal whether it replaces or adds to existing
equipment, or represents the beginning of a great new adventure.
DSLR cameras are mature products today; people in the market for one have clear
expectations and requirements. Looking forward, it seems that the EOS–1D Mark III has
everything most working photographers could want for years to come: the best autofocus,
the lowest noise and the best high ISO performance, beautiful color and excellent
resolution, ease of use and thoughtful controls, exceptional reliability, an extensive system,
highly controllable flash, and a little less weight, too.
Because the value and the performance are so strong, Canon can expect to sell the
EOS-1D Mark III to serious photographers of every stripe. Certainly, they will grow even
more delighted with the camera over time.
