Instruction
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 armful interference in a residential installation. This
ipmegenerates, uses and can radiate radio frequency
gy an, if not installed and used in accordance with the
intructions, 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:
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.
• 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 in
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.
• 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.

The innity position at normal temperature is the
nt at which the vertical line of the L mark is
agned with the distance indicator on the
distance scale.
To zoom, turn the lens’ zoom ring.
Be sure to finish zooming before focusing.

as indoors or outdoors at night.
In locations where flash
¡
photography is prohibited, such as
art museums and theater stages.
¡In situations where your

ENG-6
Image Stabilizer
¡The Image Stabilizer cannot compensate for a
blurred shot caused by a subject that moved.
¡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.
¡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:
¡Pictures may look distorted after being taken
depending on the camera, but this doesn't affect
sooting.
¡If ou 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.
• You move the camera for a panned shot.
• You shoot while riding on a bumpy road.
¡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 to
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.
