Thank you for purchasing a Canon product.
Features
1. The Image Stabilizer gives the equivalenteffect of a shutter speed four stops faster*.
This function provides optimal image
stabilization depending on shooting conditions
(such as shooting still subjects and following
shots).
2. UD lens elements for excellent imaging performance.
3. Great close-ups at 1.1 m/3.6 ft at all focal lengths.
4. A truly round aperture hole results in a nicer background blur.
*Based on [1/(focal length x 1.6)] second. Generally,
it requires a shutter speed [1/focal length] second or
faster to prevent camera shake (in 35mm format.
With an EF-S lens, it would be [1/(focal length x
1.6)] second).

aSafety 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.
• 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.
Handling Cautions• If the lens is taken from a cold environment into
a warm one, condensation may develop on the
lens surface and internal parts. To prevent
condensation in this case, first put the lens into an
airtight plastic bag before taking it from a cold to
warm environment. Then take out the lens after it
has warmed gradually. Do the same when taking
the lens from a warm environment into a cold one.
• Do not leave the lens in excessive heat such as in
a car in direct sunlight.  High temperatures can
cause the lens to malfunction.
This device complies with Part 15 of the FCC Rules. Operation is
subject to the following two conditions: (1) This device may not
cause harmful interference, and (2) this device must accept any
interference received, including interference that may cause
undesired operation.
Do not make any changes or modifications to the equipment
unless otherwise specified in the instructions. If such changes or
modifications should be made, you could be required to stop
operation of the equipment.
This equipment has been tested and found to comply with the
limits for a class B digital device, pursuant to part 15 of the FCC
Rules. These limits are designed to provide reasonable protection
against harmful interference in a residential installation. This
equipment generates, uses and can radiate radio frequency
energy and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio
communications.
However, there is no guarantee that interference will not occur in
a particular installation. If this equipment does cause harmful
interference to radio or television reception, which can be
determined by turning the equipment off and on, the user is
encouraged to try to correct the interference by one or more of
the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Consult the dealer or an experienced radio/TV technician for
help.
This Class B digital apparatus complies with Canadian ICES-003.

1Mounting and Detaching the Lens
See your camera’s instructions for details on
mounting and detaching the lens.
¡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  ¢index of the dust cap as shown
in the diagram, and turn clockwise. To remove
it, reverse the order.
2Setting the Focus Mode
To shoot in autofocus mode, set the focus mode
switch to AF.
To use only manual focusing, set the focus mode
switch to MF, and focus by turning the focusing
ring.
¡Do not touch the rotating parts of the lens while autofocus is active.
¡Do not adjust focus manually when the focus mode switch is set to AF.

3Zooming
To zoom, turn the lens’ zoom ring.
Be sure to finish zooming before focusing.
Changing the zoom ring after focusing can affect
the focus.
4Hood (Sold Separately)
The ET-60 hood can keep unwanted light out of
the lens, and also protects the lens from rain,
snow, and dust.
Turn the hood in the direction of the arrow to
attach it securely.
The hood can be reverse-mounted on the lens
for storage.
¡When attaching or detaching the hood, graspthe base of the hood to turn it. To prevent
deformation, do not grasp the rim of the hood to
turn it.
¡Part of the picture may be blocked if the hood is not attached properly.

5Image Stabilizer
You can use the image stabilizer in AF or MF
mode.
This function provides optimal image stabilization
depending on shooting conditions (such as
shooting still subjects and following shots).
1Set the STABILIZER switch to  .¡If you are not going to use the imagestabilizer function, set the switch to  .
2When you press the shutter button
halfway, the Image Stabilizer will
start operating.
¡Make sure the image in the viewfinder isstable, then press the shutter button the
rest of the way down to take the picture.
¡The Image Stabilizer cannot compensate for a
blurred shot caused by a subject that moved.
¡
The Image Stabilizer may not be fully effective if you shoot
from a violently shaking vehicle or other transportation.
¡ The Image Stabilizer consumes more power
than normal shooting, so fewer shots can be
taken if you use the function.
¡When shooting a still subject, it compensates for
camera shake in all directions.
¡ 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.
¡ When you use a tripod, the Image Stabilizer
should be turned off to save battery power.
¡
Even with a monopod, the Image Stabilizer will be
as effective as during hand-held shooting.
However, depending on the shooting environment,
the Image Stabilizer effect may be less effective.
¡The image stabilizer function also operates when the
lens is used with an Extension Tube EF12 ll or EF25 ll.
¡ 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.
