mode that is optimized for following shots of
moving subjects.
2. Aspheric and UD lens elements for truly
exceptional imaging capability.
3. Ultrasonic motor (USM) for quick and quiet
autofocusing.
4. Manual focusing is available after the subject
comes into focus in autofocus mode (ONE
SHOT AF).
5. A truly round aperture hole results in a nicer
background blur.
6. Adjustable zoom ring touch lets you lock at
any focal length.
7. Tight seal structure ensures excellent dustproof and drip-proof performance.

a Safety Precautions
a Safety Precautions
• Do not look at the sun or a bright light source
through the lens or camera. Doing so could result
in loss of vision. Looking at the sun directly through
the lens is especially hazardous.
• Do not point the lens or camera at the sun or
photograph it. This is because the lens
concentrates the sun’s rays even when the sun is
outside the image area or when shooting with
backlight, which could cause malfunction or fire.
• Whether it is attached to the camera or not, do not
leave the lens under the sun without the lens cap
attached. This is to prevent the lens from
concentrating the sun’s rays, which could cause a fire.

1. Mounting and Detaching the Lens
See your camera’s instructions for details on
mounting and detaching the lens.
The lens mount has a rubber ring for enhanced
water- and dust-resistance. The rubber ring may
cause slight abrasions around the camera's lens
mount, but this will not cause any problems. If the
rubber ring becomes worn, it is replaceable by a
Canon Service Center at cost.

• After detaching the lens, place the lens with the
rear end up to prevent the lens surface and
electrical contacts from getting scratched.
• If the contacts get soiled, scratched, or have
fingerprints on them, corrosion or faulty
connections can result. The camera and lens may
not operate properly.
• If the contacts get soiled or have fingerprints on
them, clean them with a soft cloth.
• If you remove the lens, cover it with the dust cap.
To attach it properly, align the lens mount index
and the K index of the dust cap as shown in the
diagram, and turn clockwise. To remove it, reverse
the order.

2. Setting the Focus Mode
3. Switching the Focusing
Distance Range
Y
P
O
To shoot in autofocus (AF) mode, set the focus
mode switch to AF.
To use only manual focusing (MF), set the focus
mode switch to MF, and focus by turning the
focusing ring. The focusing ring always works,
regardless of the focus mode.
C
After autofocusing in ONE SHOT AF mode, focus
manually by pressing the shutter button halfway
and turning the focusing ring. (Full-time manual
focus)
You can set the focusing distance range to
0.7 m/2.3 ft. to infinity or 2.5 m/8.2 ft. to infinity.
By setting the suitable focusing distance range,
the actual autofocusing time can be shorter.
If you autofocus outside the set focusing distance
range, the lens may stop focusing at the start of
the focusing range; however, this is not a
malfunction. Press the shutter release button
halfway again.
ENG-5
4. Zooming
5. Adjusting Zooming Resistance
Move the zoom ring forward or backward to
zoom.
• Be sure to finish zooming before focusing.
Zooming after focusing can affect the focus.
• To prevent unintended zooming when not
shooting, be careful not to set the zooming touch
too loose.
C
You can adjust the zooming “touch” (resistance)
as needed by holding the focusing ring in place
and turning the adjustment ring.
Y
P
O
Turn the adjustment ring towards the word
SMOOTH to reduce the zooming touch, or towards
TIGHT to increase it. To lock the zoom ring in
place, turn the adjustment ring towards TIGHT until
it stops.

Y
P
O
Select the stabilizer mode.
• MODE 1: Corrects vibrations in
all directions. It is mainly
effective for shooting still
subjects.
• MODE 2: It compensates for
vertical camera shake during
following shots in a horizontal
direction, and compensates for
horizontal camera shake
during following shots in a
vertical direction.
C
When you press the shutter
button halfway, the Image
Stabilizer will start operating.
• Make sure the image in the
viewfinder is stable, then press
the shutter button the rest of
the way down to take the

7. Tips on Using the Image Stabilizer
The image stabilizer in this lens is effective for hand-held shots under the following conditions.
● MODE 1
● MODE 2
C
Y
P
O
• In semi-darkened areas such as indoors or
outdoors at night.
• In locations where flash photography is
prohibited, such as art museums and theater
stages.
• In situations where your footing is uncertain.
• In situations where fast shutter settings cannot
be used.
• When panning subjects in motion.
ENG-8
Tips on Using the Image Stabilizer
• The Image Stabilizer cannot compensate for a
blurred shot caused by a subject that moved.
• Set the STABILIZER switch to
when you are
taking pictures using the Bulb setting (long
exposures). If the STABILIZER switch is set to
,
the image stabilizer function may introduce errors.
• The Image Stabilizer might not be fully effective in
the following cases:
• You shoot while riding on a bumpy road.
• You move the camera dramatically for a panning
shot in Mode 1.
• You shoot using techniques other than following
shots in Mode 2.
• The Image Stabilizer consumes more power than
normal shooting, so fewer shots can be taken if
you use the function.
• The image stabilizer operates for about two
seconds even when your finger is off the shutter
button. Do not remove the lens while the stabilizer
is in operation. This will cause a malfunction.
• With the EOS-1V/HS, 3, ELAN 7E/ELAN 7/30/33,
ELAN 7NE/ELAN 7N/30V/33V, ELAN II/ELAN
IIE/50/50E, REBEL 2000/300, IX, and D30, the
Image Stabilizer will not work during self-timer
operation.
C
• When you use a tripod, the Image Stabilizer
should be turned off to save battery power.
• The stabilizer is equally effective for hand-held
photography and photography with a monopod.
• The image stabilizer function also operates when
the lens is used with an Extension Tube EF12 ll or
EF25 ll.
• Pictures may look distorted after being taken
depending on the camera, but this doesn't affect
shooting.
• If you set the camera’s Custom Function to
change the assigned button to operate the AF, the
Image Stabilizer will operate when you press the
newly assigned AF button.

8. Infinity Compensation Mark
9. Infrared Index
Infinity Compensation Mark
Distance index
To compensate for shifting of the infinity focus
point that results from changes in temperature.
The infinity position at normal temperature is the
point at which the vertical line of the L mark is
aligned with the distance indicator on the
distance scale.
C
The infrared index corrects the focus setting
when using monochrome infrared film. Focus on
the subject manually, then adjust the distance
setting by moving the focusing ring to the
corresponding infrared index mark.
The intermediate markers between 300 and 100
are 200mm and 135mm, and the marker
between 100 and 50 is 70mm.
Y
P
O
For accurate manual focusing on subjects at infinity
distance, look through the viewfinder while rotating
the focusing ring.
Some EOS cameras cannot use infrared film. See
the instructions for your EOS camera.
• The infrared index position is based on a
wavelength of 800 nm.
• The compensation amount differs depending on
the focal length. Use the indicated focal length as
a guide when setting the compensation amount.
• Be sure to observe the manufacturer’s
instructions when using infrared film.
• Use a red filter when you take the picture.
