I. OVERVIEW
The new Canon EOS 40D welcomes users to the next generation of Digital SLR photography
by continuing the Canon traditions of exceptional performance, quality and value. The
EOS 40D has a newly-enhanced 10.1 megapixel CMOS sensor that takes advantage of
Canon-developed manufacturing techniques to achieve fine detail, high image quality,
and low noise. The output from the sensor is converted to 14 bits, rather than 12, for
finer color gradation. Highlight Tone Priority improves exposures in difficult lighting conditions.
The EOS 40D is really fast, too. It fires those 10.1 megapixel, 14-bit files at 6.5 frames
per second, shooting continuously with 75 shot bursts of Large/Fine JPEGs or 17 RAW
images. The speed comes from the powerful combination of the new DIGIC III processor,
DDR SDRAM high-speed memory, 4-channel per line sensor readout, and 2 separate
motors for shutter and mirror operation. The EOS 40D has a top shutter speed of
1/8000 sec., X-sync at 1/250 sec., a 0.15 sec. startup time and ISOs to 3200 (using the
extension feature). High ISO noise reduction maintains image quality with low-light shooting.
The EOS 40D is accurate. It has a completely new AF sensor with 9 cross-type AF points
and an innovative center AF point sensitive to vertical and horizontal lines at f/2.8.
Live View Function opens up a whole range of new possibilities for camera operation
and placement, either looking at the camera’s new, large 3.0-in. LCD monitor, or viewing
and firing remotely using the new Wireless File Transmitter WFT-E3A.
The EOS 40D is easy to use and eminently convenient. It has a bright, high-magnification
viewfinder with a broad field of view. The Self Cleaning Sensor Unit with Dust Delete
Data takes care of most dust-related problems. Image display and navigation are now
simpler and have more options, and Camera Direct printing has been enhanced.
The EOS 40D is remarkable in its ability to be configured according to the taste and
requirements of the user. It has new, interchangeable focusing screens, Picture Style
settings, camera setting registration, an AF Start button, and a host of Custom
Functions. Moreover, the EOS 40D’s magnesium alloy body and stainless steel chassis
make it rugged and feel great in the hand.
The 40D is a camera that will appeal to a vast range of photographers from advanced
amateurs to working photojournalists and wedding photographers. All will appreciate its
exceptional image quality, ease of operation, speed, modest weight and size, compatibility
with the vast Canon system and very reasonable price. This paper will examine the EOS
40D in detail and show exactly why it is such an important and appealing product.

II. SUMMARY OF NEW AND IMPROVED FEATURES

The CMOS sensor in the EOS 40D has been
designed and developed by Canon, and is made by
Canon using semiconductor manufacturing equipment that was also designed and manufactured by
Canon. The performance and value benefits that
result from this integration are enormous. The EOS
40D boasts the highest performance in its class:

* Standard output sensitivity. Recommended exposure index.
Although the EOS 40D’s single-piece CMOS sensor is based on the Canon EOS Digital
Rebel XTi’s sensor design and manufacturing technology, new processes were incorporated
in the CMOS semiconductor fabrication and microlens-forming process. By improving
light-collecting efficiency, the same ISO range and low noise (S/N ratio) as that of the
EOS 30D were attained even though the pixels on the 30D are larger.

The combination of 4-channel reading per line and high-speed signal reading (about
twice as fast as the EOS 30D, which also has 4-channel reading), together with a
redesigned 2 motor system for charging the reflex mirror and shutter independently (see
page 13), enables approximately 6.5 fps continuous shooting.
III. PERFORMANCE

DIGIC III and 14-bit A/D
Conversion
Following its appearance on the EOS-1D Mark III (in tandem form), the EOS 40D also
uses Canon’s latest image processor, the DIGIC III. It retains the DIGIC II's widely
admired image detail, natural colors and high speed, while providing 1.7 times faster
signal processing speed.
The analog output signal from the imaging element is converted into a digital signal
with 14 bits (16,384 colors) per channel instead of the previous 12 bits (4,096 colors).
The result is digital data with finer gradation. With RAW/sRAW images recorded at 14
bits, one can use Canon DPP (Digital Photo Professional) software to process and save
the image as a 16-bit TIFF image. This yields the maximum range of colors afforded by
14-bit processing. Also, because images recorded in JPEG (8 bits per color) are also
generated from 14-bit RAW data, there are fewer blown highlights than before and
gradation is excellent. Even in the case of highly saturated subjects or subjects with
high contrast and clear differences between light and dark features, high quality color
reproduction and smooth tone rendition from highlights to shadows are possible.
Image Recording and
Processing
When compared to the EOS 30D, the image quality of the EOS 40D is appreciably better.
Resolution is now higher, with approximately 10.1 megapixels versus the 8.2 megapixels
of the EOS 30D. Image quality is higher because of the DIGIC III and 14-bit image processing. Noise reduction of high ISO shots, first offered on the EOS-1D Mark III, is
enabled via C.Fn II-2. Highlight Tone Priority (ISO range 200-1600*), makes gradation
finer from grays to highlights, reducing the likelihood of blown high values. This feature,
too, first appeared on the EOS-1D Mark III. It is set on the EOS 40D via C.Fn II-3.

The number of possible shots (battery life) and continuous shooting speed are based on Canon’s testing
standards and a 1GB CF card. The size of one image, number of possible shots (battery life), and continuous shooting speed are based on JPEG quality 8, ISO 100, and the Standard Picture Style. (These figures vary depending on the subject, memory card brands, ISO speed, Picture Style, etc.)
III. PERFORMANCE
6
The Picture Style function has the same specifications as
Picture Style Screen
those of the EOS 30D, but the EOS 40D is also compatible
with Canon’s new Picture Style Editor software, which allows
even more control over image quality (see page 26 for
details). The EOS 40D has a separate Picture Style selection
button to the left of the power switch to make selection easier.
Next to the Picture Style button is the INFO. button which accesses the parameter setting
screen. The buttons improve the ease of selecting and adjusting the Picture Style.
CF card access speed is now 1.7 times faster, thanks to
DIGIC III Image Processor, and additional measures have
been taken to keep image data intact while it is being written
to the memory card. With the EOS 30D, if one opens the CF
card slot cover while data is being written to the CF card,
image data would be erased. However, with the EOS 40D
Open-cover Warning Screen
(and the EOS-1D Mark III), data writing continues even if the CF card slot cover is
opened. If the slot cover is opened, the beeper will sound and a warning screen will be
displayed until the cover is closed.
Also, if the power switch is turned off while data is being written to the CF card, a warning
screen is displayed during the writing. When the writing ends, the camera turns off.
During image deletion, images to be discarded are marked with checks. A useful new
function permits the deletion of all checked images simultaneously.
As with the EOS-1D Mark III, image recording can be set to
Recording Function
[Standard], [Auto switch media], [Rec. separately], or [Rec. to
multiple]. The optional settings are used when an additional
USB storage device is connected to the EOS 40D via
Wireless File Transmitter WFT-E3A (see page 32).
Images in the CF card can be backed up to external media
via the WFT-E3A as mentioned above. Besides the quick
backup feature also found in the EOS-1D Mark III, the folder
to back up the images can be created or selected. Only
Backup
checkmarked images can be backed up.
Auto ISO
A new feature, Auto ISO speed, is enabled in the Creative
Zone modes. When the ISO is set to [Auto], ISO 400 is set initially. Then, depending
upon the lighting conditions, ISO speed is selected automatically (in 1/3-stop or wholestop increments) as shown in the accompanying table. The resulting shutter speed is a
function of the brightness level such with an aim towards reducing blur caused by camera
shake, and also to ensure that the subject does not appear too bright or too dark
because of overexposure or underexposure.

The automatically-set ISO speed is displayed in the viewfinder and on the LCD panel
while the metering is active. In the Basic Zone modes, the automatically-set ISO speed
range is 100-800,* 1 stop greater on the high end than with the EOS 30D.
* Standard output sensitivity. Recommended exposure index.
High ISO Noise Reduction
Long exposure noise reduction is equal on the EOS 40D and 30D cameras. [Off], [Auto],
or [On/always applied] can be selected. The time required for noise reduction processing is equal to the duration of the original exposure; the next photograph cannot be
shot until noise reduction processing in progress is complete.
High ISO noise reduction (C.Fn II-2) can be used for images taken at a high ISO speed,
as with the EOS-1D Mark III. Although some noise reduction is applied at all ISO speeds,
it is particularly effective at high ISO speeds. However, at low ISO speeds, noise in the
shadow areas is, in fact, further reduced. Also, when [High ISO speed noise reduction]
is set, the maximum burst during continuous shooting will decrease to 8, regardless of
the image-recording quality.
Highlight Tone Priority
Highlight Tone Priority seeks to improve highlight detail. The range is extended between
18% (“middle”) gray and the maximum highlight tone. This makes the gradation finer
from the grays to the highlights and reduces blown highlights. The function limits the
settable ISO speed range to 200-1600.*
* Standard output sensitivity. Recommended exposure index.

White Balance
Auto Brightness and
Contrast Correction
The white balance settings are basically the same as those of the EOS 30D. Only the
color temperature (P) as a preset WB is new. The lowest manually selectable color
temperature has been lowered from 2800K to 2500K in order to cover tungsten light
more effectively. One can now register one setting of personal white balance under <O>
with the provided software. WB correction and WB bracketing settings can now be
canceled with the INFO. button.
In Basic Zone modes, when the image is processed internally (i.e. not RAW or sRAW),
image characteristics are detected and are now adjusted automatically during processing
to obtain optimized brightness and contrast.
Sample Adjustment of Brightness and Contrast
Table 13 Sample adjustment of brightness and contrast
Underexposed AE
Underexposed flash
* In bright scenes such as at the beach and on ski slopes,
underexposure tends to result. The automatic adjustment
makes the highlights brighter, resulting in a more natural
looking brightness.
* When the subject is beyond the range of the flash and becomes
underexposed, the automatic adjustment makes the highlights
brighter. This results in a standard flash exposure.
Low contrast
* In the case of low-contrast, hazy scenes, the contrast is adjusted to
obtain a clearer and more distinct image.
EOS Integrated
As in the examples of the EOS-1D Mark III and the EOS Digital Rebel XTi, the EOS 40D
Cleaning System
incorporates the highly practical EOS Integrated Cleaning System to help prevent dust
generation and adhesion of dust to the low-pass filter. Although it is basically the same
system as the one employed in the EOS-1D Mark III, the Self Cleaning Sensor Unit is a
3rd-generation design that uses only 1 piezoelectric element instead of 2, and the unit
is optimized for the smaller APS-C size instead of the larger APS-H size.
The self-cleaning operation can be executed automatically during power on/off, with an
operation time of approximately 1 sec., or manually with an operation time of approximately 3.5 sec. Dust Delete Data is acquired when the coordinates of dust adhering to
the low-pass filter are detected by a test shot and appended to subsequent images. The
dust coordinate data appended to the image is used by the provided software DPP to
erase dust spots automatically. Dust removal performance and Dust Delete Data
specifications are the same as those of the EOS-1D Mark III.
III. PERFORMANCE

The [Sensor cleaning] menu is basically the same as the one in the EOS-1D Mark III.
However, there are slight differences such as the shutter operation sequence for [Clean
now]. For the EOS-1D Mark III, it is: Cleaning operation -> Shutter cocking -> Cleaning
operation -> Shutter cocking -> Cleaning operation. In the EOS 40D, it is: Cleaning operation -> Shutter release -> Cleaning operation.

precision and extreme-defocus subject detection capability.
AF sensitivity is now EV -0.5 to EV 18. All AF points work as
cross-type points at f/5.6 or better. Both vertical- and horizontal-line sensitive focus detection thus works with any AF point for stable focusing.
High-precision AF is attained with fewer AF failures with hard-to-focus subjects. Also, with
the sensor pitch reduced from 16µm to 14.4µm, detection performance is more accurate.

The positioning of the AF points is almost the same as with the EOS 30D's AF sensor.
The center AF point has a cross-type AF sensor sensitive to vertical and horizontal lines
at f/2.8. This is a first in an EOS camera. Previously, the central sensor for f/2.8 or better
was only vertical-line sensitive. Because the f/2.8 sensor is a diagonal, cross-type sensor,
it does not obstruct the f/5.6 sensor positioned vertically at the center.
The upper center, center, and bottom 3 horizontal-line sensitive sensors are in a 2-line,
zigzag configuration. With this double focusing system, inconsistent focusing detection
is reduced. By using the 2-line focusing sensors described above, a subject in extreme
defocus can be detected and AF control is quick and easy.
To attain more stable AF performance than before, the
AF unit has more precise AF optics and environmentresistant construction and materials.

The AF modes are the same as those of the EOS 30D:
One-Shot AF, AI Focus AF, and AI SERVO AF. Any of
these settings can be selected in Creative Zone shooting
modes. One-Shot AF is set automatically in the Portrait,
Landscape, Close-up, and Night Portrait modes. AI Focus AF (switches between One-Shot
AF and AI SERVO AF automatically) is set automatically in Full Auto and Flash Off modes.
Predictive AI Servo AF is set automatically in Sports mode. The EOS 40D can, of course,
also be focused manually in any shooting mode.

Compared to the EOS 30D, the EOS 40D’s focusing calculation
speed is 1.3 times faster, and the AF data-processing time is
shorter. Predictive AF can track a subject approaching at 50
kph/31 mph up to about 26.2 ft./8m away with an EF
300mm f/2.8L IS USM lens.

Because subject detection has been improved with all
cross-type AF points, high-speed continuous shooting in
the AI SERVO AF mode is more stable than with the EOS 30D, and it is also done at a
faster framing rate (6.5 fps vs. 5.0 fps).

The algorithm for automatic AF point selection in the EOS 40D is the same as the EOS
30D's. However, because all the AF points are now cross-type sensors, subject detection
is improved, making the AI SERVO AF subject-tracking performance better. Also, in the
One-Shot AF mode, the probability of capturing the subject as intended is increased.

Alternatively, certain accessory

As with the EOS 30D, one can use the Multi-controller or Main/Quick Control dial (C.Fn
III-3-1/2) to select the AF point while looking at the superimposed AF point in the
viewfinder or the LCD panel's AF point selection display. Also as with the EOS 30D, the
AF mode (One-Shot AF, AI Focus AF, AI SERVO AF) is selectable even in the Creative Zone
modes. The provision of an <AF-ON> button is a feature from the EOS-1D Mark III.
Alternately, one can press the shutter button half way to activate the AF.
Drive
The EOS 40D has the highest continuous shooting speed in its class†, approximately
6.5 fps in both One-Shot AF and AI SERVO AF modes. Despite increased resolution and
its concomitant increase in file size, this exceptional speed and a stable viewfinder
image are attained by combining several technologies. The powerful new DIGIC III
processor and 4-channel sensor readout have been mentioned here already. The buffer
memory of the EOS 40D is DDR SDRAM (double data rate, synchronous dynamic random
access memory) for high-speed reading and writing, whereas the EOS 30D used the
slower SDRAM.
† As of August 2007.
Two-Motor System
Of considerable importance, the EOS
40D uses a 2-motor system, one
dedicated to driving the mirror, and
one dedicated to cocking the shutter
speedily. Also, a stopper is incorporated to prevent the rebounding or
bouncing of the main mirror and
secondary mirror. This results in shorter
viewfinder blackout and a more stable
viewfinder image during continuous shooting.

their maximum performance, the maximum burst at approximately 6.5 fps is approximately 75 shots in JPEG Large/Fine and approximately 17 shots in RAW. By comparison,
the maximum bursts for the EOS 30D were 30 Large/Fine JPEGs and 11 RAW. (These figures
are based on Canon's testing standards with a 1GB CF card. The maximum burst during
continuous shooting varies depending on such factors as subject, CF card brand, ISO
speed, and Picture Style.)
In Low-speed continuous drive mode, the EOS 40D fires at approximately 3 fps. The
drive mode selection loop now includes a 2-sec. self-timer.
Shutter
While it is based on the EOS 30D's mechanical shutter unit, the shutter of the EOS 40D
is now more reliable with a contactless switch instead of a contact switch for running
the 1st and 2nd curtains. Shutter durability is approximately 100,000 cycles, the same
as the EOS 30D's shutter. The shutter release lag time with SW-1 ON is approximately
0.059 sec. between SW-2 ON and start of exposure. The time lag between simultaneous
SW-1/SW-2 ON and the start of exposure is approximately 0.126 sec. Time lag is calculated
with the aperture stopped down 3.5 stops or less and excludes AF operation time.
Viewfinder blackout time is about 0.1 sec.
The self-timer now offers a choice of
2 sec. or 10 sec. delay. The shorter
time is useful for eliminating blur
caused by the camera shake associated

In addition to the mechanical shutter, the EOS 40D has a 1st curtain electronic shutter
that is a key component in the Live View Function.

the 40D meets both criteria, absence of cut-off
as well as visibility of both image and information. The basic configuration of the superimposed display optics is the same as that of the EOS 30D.
Interchangeable focusing screens are a new and significant feature of the EOS 40D. The
Ef-series focusing screens have been newly developed. 3 screens, the Ef-A Standard
Precision Matte, the Ef-D Precision Matte with Grid, and the Ef-S Super Precision Matte
are available. All 3 focusing screens have a fresnel lens area and are produced by a new
molding method (first used on the EOS-1D Mark III’s focusing screen Ec-C IV) that provides
excellent transfer characteristics. Consequently, even the Standard Precision Matte

screen offers improved performance. The Grid Type screen is particularly convenient for
controlling horizontal positioning and as an aid to overall composition. The Super-Precision
screen makes it easier to find the “sweet spot” of focus when using a lens that is faster
than f/2.8 and is also effective in difficult, manual focus conditions.
The information display inside the finder has been enhanced in several ways: the ISO is
always displayed, even when Auto ISO is set; a Black and White setting alert has been
added; and the maximum burst possible is displayed in two digits instead of one. The
LCD monitor can also be used to display the settings of the shooting functions.
Live View Function
One of the major aspects of the EOS-1D Mark III is the inclusion of a fully-functional Live
View Function. The EOS 40D has it as well, along with some useful improvements. In
addition to the Live View Function found in the EOS-1D Mark III, the EOS 40D enables
"AF during Live View Function" and "Silent shooting." (Note: Live View Function is only
possible with the Creative Zone modes.)
The EOS 40D's CMOS sensor has an electronic 1st-curtain shutter function, enabling
shooting with the mechanical shutter completely open. With Live View Function image
displayed, the 40D can shift seamlessly to slit exposures with the electronic 1st-curtain
shutter, enabling silent shooting which is not possible with a mechanical 1st-curtain
shutter. This electronic 1st-curtain shutter uses a unique high-speed scanning and electronic reset system that accurately mimics the EOS 40D's high-speed mechanical shutter
III. PERFORMANCE
14
operation. It synchronizes with the mechanical 2nd-curtain shutter to obtain a slit exposure.
(Note that with CMOS, it is difficult to have an electronic 2nd-curtain shutter. Therefore,
only the 1st-curtain shutter is electronic.)
As a result of the electronic 1st-curtain shutter, the [Silent shoot] Modes 1 and 2 make
the shutter-release time lag shorter and reduce shutter-cocking noise. Mode 1 enables
continuous shooting at approximately 6 fps and is quieter than ordinary, non-Live View
shooting. Continuous shooting is not possible with Mode 2. With Mode 2, shutter cocking
does not occur after shutter release, but only when the shutter button is SW-2 OFF. At
most, only the shutter curtains make noise, and the shutter sound during the exposure
can be limited to the quieter mechanical 2nd-curtain
Silent Shooting
shutter. Live View Function with the EOS-1D Mark III had
the shutter closing after the shutter release before the
start of the exposure. This caused shutter-release time
lag and shutter-cocking noise.
Pressing the AF-ON button pauses the Live View
Function; the reflex mirror goes down and the camera
executes AF. Letting go of the AF-ON button resumes the
Live View Function. With C.Fn III-6, the set AF mode and
AF point (automatic selection possible) will be applied
during AF while one holds down the AF-ON button.
C.Fn III-6
Note that during this time, there will be no Live View Function image displayed since the
reflex mirror will be down. Since no AF points are displayed on the screen with Live View
Function, positioning the magnified display's focusing
AF During Live View Function
frame at the center and selecting the center AF point for
autofocusing is recommended. During AF operation, shutter release is not possible. One must first release the AFON button and wait until the image with Live View
Function is displayed, then shoot.
With the CMOS sensor's electronic 1st-curtain shutter, shooting is possible while the
image with Live View Function is displayed and the mechanical 1st curtain is open. The
mechanical 1st curtain need not be closed in order to shoot. This eliminates the
mechanical 1st curtain's shutter sound at SW-2 ON which occurs with the EOS-1D Mark III
during Live View Function. Silent shooting is therefore possible.
As in the case of the EOS-1D Mark III's Live View Function, the exposure is controlled
with the mechanical shutter's 1st and 2nd curtains. Set to "Disable" when using a TS-E
lens shifted up or down or when using an Extension Tube. If one sets Mode 1 or Mode 2
when using a TS-E lens and a shutter speed of 1/2000 sec. or faster, the small slit created
between the electronic 1st-curtain shutter and mechanical 2nd-curtain shutter will be in
the same orientation as the optical axis, resulting in underexposure or overexposure.
III. PERFORMANCE
15
Similarly, with an Extension Tube and a shutter speed of 1/2000 sec. or higher, the
exposure will be uneven at the top and bottom of the image.
When using an EX-series Speedlite, the
shooting sequence will be the same as
the EOS-1D Mark III's Live View

Live View Function Metering Timer
The Live View Function metering timer is geared mainly
for still-life subjects. Live View Function enables the
metering timer to be changed to one of 6 settings from 4
sec. to 30 min.
Two useful features of Live View Function in the EOS-1D Mark III that appear in the
EOS 40D are:

° Time lag figures above apply with the aperture stopped down by up to 3 stops (reflex
mirror operation time excluded).
• Remote Live View Function: enabled with EOS Utility, outputs Live View Function video
for viewing on computer monitor, improves remote shooting by making it possible to
check such things as composition, focus, moiré, and false colors
III. PERFORMANCE

Exposure Control
The EOS 40D uses the same 35-zone metering sensor as in the
EOS 30D. The metering modes are evaluative, partial (approximately
9% of viewfinder area), spot (approximately 3.8% of viewfinder
area), and center-weighted average metering.
Metering Sensor
Previously, during automatic AF point selection and AF point-centered
evaluative metering, there was a tendency for slightly excessive compensation. The
compensation is now looser so that exposure is more consistent.
The E-TTL II autoexposure algorithm of the EOS 40D is the same as the EOS-1D Mark III's
E-TTL II autoexposure algorithm. By optimizing the method of using lens distance
information, exposure becomes more accurate for highly reflective subjects. With the
EOS 30D, the selected metering mode was used to meter the ambient light. This sometimes
resulted in inaccurate exposures when the selected metering mode was not evaluative
metering. Therefore, as with the EOS-1D Mark III, evaluative metering is now used at all
times to meter the ambient light.
The EOS 40D uses the same exposure control system as the EOS 30D, with eleven AE
modes and manual mode. While based on the EOS 30D's shutter unit, the 40D’s shutter
is now more reliable with a contactless switch instead of a contact switch for running
the 1st and 2nd curtains. Shutter durability is approximately 100,000 cycles, the same
as with the EOS 30D’s shutter. With a fully-charged Battery Pack BP-511A, the shutter
supports a bulb exposure as long as about 2.5 hours.
Flash
A new feature, shared with the EOS-1D Mark III, and a considerable convenience, is that
both built-in flash and external Speedlite settings can be set on the EOS 40D from the
camera with the menu screen. With external, EX-series Speedlites, this includes Flash
mode, sync setting, FEB, flash exposure compensation, E-TTL II, zoom, wireless flash,
and clear settings. The EOS 40D can make communication settings as well, such as
communication channel, flash group, and flash brightness
when the Speedlite 580EX II is used. Also, with the 580EX II
attached to the camera, one can set or cancel the Speedlite's
Custom Function settings (C.Fn-0 to 13) with the camera. With
an EX-series Speedlite other than the 580EX II, the camera cannot be used to set the Speedlite's Custom Functions.
External flash Custom Function
The flash unit in the EOS 40D is the same as the unit in the EOS 30D. Its Guide Number
is 43/13 at ISO 100 in feet/meters. Flash coverage is effective for focal lengths 18mm
and higher, with some limitations based on the size of the lens. If the built-in flash is
fired rapidly in succession, the flash firing will be stopped to prevent heat damage to
the built-in flash cover and fresnel lens (diffuser). In the case of the EOS Digital Rebel
XTi, which has similar specifications, if the built-in flash is fired 20 times successively at
10 sec. or shorter intervals, the firing will be stopped. With the EOS 40D, the flash control
is more precise, so the flash stoppage is less likely to occur than with the EOS Digital
Rebel XTi.

LCD Monitor
The EOS 40D has a 3.0-in. TFT liquid-crystal color LCD monitor with approximately
230,000 pixels and a wide, 140º viewing angle, both horizontally and vertically. Note
that the viewing angle has actually been reduced from 170º on the EOS 30D to improve
ease of viewing outdoors, and that the screen’s brightness level has been increased for
the same reason. Also, the color gamut has

been broadened. Brightness is adjustable to
any of seven levels. The larger monitor size
means a larger font size can be used for
menu display. In all, the LCD monitor is easier
to use and more accurate than before.
Design and Construction
Like the EOS 30D, the main exterior covers (top, front, and rear) are made of magnesium
alloy for light-weight and high strength. The grip portion is integrated with the front
cover, enhancing body rigidity further. The body's basic construction is the same as that
of the EOS 30D, employing a stainless steel chassis and a mirror box made of highstrength engineering plastic. As with the EOS 30D, the exterior has a high-quality, black
satin finish with a non-slip texture. The EOS 40D also
has sealing material lining the CF card slot cover and

battery compartment cover (which is not found in the
30D) to improve dust- and water-resistance. The EOS
40D has sealing material lining the CF card slot cover
and battery compartment cover to improve dust- and
water-resistance. The battery compartment covers of
both the Battery Grip BG-E2N and the Wireless File
Transmitter WFT-E3A have sealing material to improve
resistance to dust and water.
The configuration of the major components is basically the same as in the EOS 30D,
with the exception of the following units which have been added or changed:
• Self Cleaning Sensor Unit
• LCD monitor made bigger from 2.5 in. to 3.0 in.
• Two driving motors to attain approximately 6.5 fps continuous shooting speed
• Extension system terminal

• EEPROM memory to store saved data such as adjustment data (AE, AF, etc.)
The bottom board is a highly integrated, 4-layer board containing:
• The flash circuit and actuator drive circuit
• The flash circuit which controls the built-in flash's recycling and firing and the external
Speedlite control circuit
• The 2-motor control circuit that drives the mirror and shutter-driving actuator
• The lens power supply control circuit
• The Self Cleaning Sensor Unit's actuator drive control circuit

File Transmitter WFT-E3A and link-ups with Picture Style Editor.
“Picture Style” was first included as part of EOS Digital in the fall of 2005. Since then, it
has become a standard feature in EOS Digital and will be incorporated into the entire
current EOS product range in the latter half of 2007. These features, namely:
• the standardization of image characteristics across all EOS Digital models
• optimized support for photographic expression according to purpose
• support for RAW images shot on older models in DPP
• support for web downloading of Picture Style files according to purpose,
have been very well received by users. That said, there have also been calls from
advanced users with particularly stringent demands in terms of image processing for
even more flexible adjustments that go beyond the preset characteristics supplied by Canon.
The Picture Style Editor, as the name suggests, is software that allows users to create
their own Picture Style files. To create his or her own Picture Style file, the user selects
and loads a sample RAW image and then adjusts the image characteristics based on
one of the existing Picture Style settings (Standard, Portrait, Landscape, Neutral or
Faithful) except for Monochrome. The created Picture Style file can then be registered in
the camera using EOS Utility or used in the DPP or RAW Image Task applications.
Settings that can be
adjusted in Picture Style
Editor:
a. Existing Picture Style Detail settings: Color Tone, Color saturation, Contrast and
Sharpness adjustments
b. Color specification and individual minute adjustments to specified colors: selection
of a specific color in the sample image and adjustment of the hue, saturation and
Luminosity, as well as minute adjustments to the gamma characteristics (tone curve)
V. SOFTWARE
26
The settings in a. were previously available either on the camera or in EOS Utility, so
that the results of any adjustments had
PSE Main Window and Tool Palette
to be checked later after the picture had
actually been taken. With Picture Style
Editor, the results of adjustment can be
checked in real time. The adjustments in
b. are available for the first time (with
real time checking) with Picture Style
Editor. Up to 100 color points can be
selected in the color specifications
provided in b.
Picture Style Editor ver.1.0 supports RAW images shot
only on the EOS 40D. (Future versions will support future
EOS models, but no reverse compatibility to older EOS
Preliminary Adjustment Window
models is planned.) Picture Style Editor has a Preliminary
Adjustment window for images that need supplementary
adjustment.
For images shot with the correct exposure/white balance, there is no need to use
preliminary adjustment.
The editing window consists of 3 components:
Main Windows in PSE
• Main window: Displays the sample image
• Navigator window: Displays the position of a magnified
image and also displays histograms
• Tool palette: Provides the adjustment functions
Because the adjustments made using the tool palette
functions are applied immediately to the sample
image shown in the main window, one can check the
results in real time.

Adjusting the Gamma Characteristics
29
One can save all the adjustments one has made with the tool palette as an original
Picture Style file (with the .PF2 extension). (Because adjustments made in Picture Style
Editor are saved in Picture Style files, they are not saved in the sample image used for
the adjustment process.) Adjustments are saved in the save window, which appears
when you click the save window display button in the tool palette. When one saves the
file, there is a [Disable subsequent editing] checkbox that prevents disclosure of the
adjustments made in Picture Style Editor as well as any captions or copyright information. Picture Style files that have been saved with the [Disable subsequent editing]
checkbox ticked can be used in cameras and in DPP in the same way as ordinary Picture
Style files. However, because they can no longer be opened in Picture Style Editor, one
cannot check the adjustments. (We recommend also saving a separate copy of the
Picture Style file without the [Disable subsequent editing] checkbox ticked.)
Like purpose-made Picture Style files downloaded from the Canon website, saved
Picture Style files can be registered and used in cameras and used in the DPP and RAW
Image Task applications.
(1) Using Picture Style files in cameras: One can use EOS Utility to register a Picture
Style file in a camera equipped with the Picture Style function and then apply the file
to photographed images.
(2) Using Picture Style files with DPP: One can use DPP to apply Picture Style files to any
compatible RAW image.
(3) Using Picture Style files with RAW Image Task: One can use RAW Image Task to apply
Picture Style files to RAW images shot on cameras equipped with the Picture Style
function.
Picture Style Editor will be included on EOS Digital Solution Disk ver.15. Later this year,
Picture Style Editor will be available as a download for all EOS users from the Canon
website.

VI. ACCESSORIES AND LENS
Battery Grip BG-E2N
The BG-E2N is a high-capacity battery grip dedicated to the EOS 40D. It was developed to
enable high-volume shooting and easier vertical shooting. It can accommodate the BP-511A
as well as AA-size batteries.
In terms of function, the BG-E2N is the same as Battery Grip BG-E2 for EOS 30D, 20D, and
20Da. However, the battery compartment cover now has sealing material to make it more
resistant to dust and water than the BG-E2. The power source and method are the same
as with the BG-E2. With the introduction of the BG-E2N, the BG-E2 will be discontinued.
Therefore, the BG-E2N will be the battery grip for the EOS 30D, 20D, and 20Da henceforth.
When the BG-E2N is attached to these cameras, the continuous shooting speed and
number of possible shots will be the same as with the BG-E2.
Features:
(1) The EOS 40D
(with BP-511A x 2) enables
about twice as many shots to

Wireless File Transmitter
WFT-E3A
The WFT-E3A is a dedicated EOS 40D accessory
similar to the WFT-E2A (the wireless file transmitter
unit for the EOS-1D Mark III) offering wireless or
wired network functions (via FTP, PTP, or HTTP)
and support for USB peripherals (specifically,
external storage devices and GPS units). There
are 2 main differences from WFT-E2A: inclusion
WFT-E3A
of controls for vertical shooting and inclusion of
the unit’s own power supply. Compared with the
WFT-E1A, communication speed is 1.5x faster
(wireless) and 3x faster (wired).
For better control of the EOS 40D when shooting
with the WFT-E3A attached, the unit provides
vertical grip functions. In the same way as when
a battery grip such as a BG-E2N, is attached, the
WFT-E3A feels well integrated with the camera.
The internal antenna offers a wireless range
equivalent to that of the WFT-E2A, up to about
492 ft./150m. Like the battery grip, the WFT-E3A
attaches to the camera’s tripod socket.
Wireless and wired LAN function specifications
are the same as for WFT-E2A. Note that the camera
graphic on the WFT Server screen during HTTP
connections has been updated from EOS-1D
Mark III to EOS 40D. Requirements for external
media or GPS devices that can be connected are
the same as for the WFT-E2A. Note that images
cannot be copied between media.
Features:
• Ideally shaped; does not interfere with shooting:
° Attaches directly to the bottom of the EOS 40D (cordless)
° Internal antenna (wireless range: approx. 492 ft./150m)
• Faster image transfer:
° Wireless networks: 1.5 times faster than WFT-E1A (IEEE 802.11g)
° Wired networks: 3 times faster than WFT-E1A (Ethernet 100 Base-TX)
VI. ACCESSORIES AND LENS
32
• Offers FTP, PTP, and HTTP communication modes:
° FTP: Image transfer over wireless or wired networks to an FTP server
° PTP: Communication between EOS Utility and the camera over wireless or wired networks
° HTTP: Remote capture over wireless or wired networks using a web browser
• Better user support in configuring wireless or wired network settings:
° Wizard-based configuration of transfer settings through the camera GUI
° Includes features for network detection and automatic setup (access point detection
and automatic acquisition of IP address)
° Supporting software for PTP connections
• Compatible with external storage devices and GPS units (USB connection):
° Users can connect external hard disks or other external storage devices
° GPS data can be added to images
• Includes controls for vertical shooting
Focusing Screen Ef
The Ef-series focusing screens are interchangeable focusing
screens developed for the EOS 40D. 3 types are available: Ef-A
Standard Precision Matte, Ef-D Precision Matte with Grid, and Ef-S
Super Precision Matte to make it easy to see the point of focus.
The optical characteristics of the Ef-A and Ef-D focusing screens
are the same as the Ee-A and Ee-D focusing screens. The optical
characteristics of the Ef-S focusing screen are the same as the
Ef-A Standard Precision Matte
Ef-D Precision Matte Grid
Ec/Ee-S focusing screens. The focusing screen can be installed in
the same way as previous focusing screens. However, to make
Ef-S Super Precision Matte
them easier to install, a dedicated tool has been newly developed.
The tool case is the same as the one for Ec/Ee focusing screens
and has a paper partition matching the Ef-series focusing screen.
The Ef-series focusing screens are smaller than the old focusing
screens. The new installation tool is longer than the old one with the lever more toward
the rear, making it easier to install and remove the new focusing screen.

New IS Lens
The Canon EF-S 18-55mm f/3.5-5.6 IS is a standard zoom
lens specifically for cameras that take EF-S lenses. It was
developed in response to market demand for a zoom
lens equipped with Image Stabilizer technology at a
reasonable price.
The advantages of IS in the lens are, first, that each IS
system can be designed and optimized for its specific
application, yielding a level of performance unattainable
by the in-body, shifting sensor technique. Second, one
can see the image stabilization effect in the finder. The
image is steady; accurate framing is possible; the AF
point can be placed precisely, and the photographer can
concentrate on the shot and capture the best moment.
Panning is also easier and more effective than with the
Image Stabilization with Shifting Elements

• Uses smaller circuit boards and a downsized IS unit to make a Canon Image Stabilizer
lens that is roughly the same size and weight as the EF-S 18-55mm f/3.5-5.6 II/ f/3.55.6 II USM
• High-speed autofocus features high-speed
CPU and optimized AF algorithm
• Image Stabilizer effect equivalent to a
shutter speed about 4 stops faster
• Uses a high-precision PMo aspherical

IX. CONCLUSION
No product can be perfect for everyone, but the EOS 40D comes pretty close. It has
immense appeal to advanced amateurs because of its exceptional image quality
combined with an unintimidating and convenient operating system. Its reasonable size
and weight will travel well (a plus for professionals, too) and fit smaller hands comfortably.
All prospective EOS 40D owners will see a 10.1-megapixel camera that fires long bursts
compatible with a vast system of existing pro-grade gear, and makes superb images in
almost any light. The heart of the argument? The EOS 40D costs thousands of dollars
less than other cameras with fewer features and inferior image quality. It is certain to
become a mainstay for entry-level professional photographers and advanced amateurs
of virtually every description, as well as a reliable back-up for other pros, who for
business and common sense reasons, would prefer less expensive hardware that still
gets the job done superbly.
The Canon EOS 40D is a great camera at a great price and is certain to satisfy legions of
photographers worldwide.
