a Safety Precautions
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.
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 ca
attached. This is to prevent the lens from

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:
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.
• 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.

See your camera’s instructions for details on
mounting and detaching the lens.
• After detaching the lens, place the lens with the

fingerprints on them, corrosion or faulty
connections can result. The camera and ens

6. 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
• In semi-darkened areas such as indoors or
outdoors at night.
• When panning subjects in motion.
• 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.
ENG-7
Tips on Using the Image Stabilizer
• When using a tripod, set the STABILIZER switch
to prevent errors.
• The Image Stabilizer cannot compensate for a
blurred shot caused by a subject that moved.
• 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 the EF12 II or EF25
II Extension Tube, and the EF1.4X II Extender.
•
Set the STABILIZER switch
using a tripod. If the Stabilizer switch is set to
the image stabilizer function may introduce errors.
Set the STABILIZER switch to
taking pictures using the Bulb setting (long
exposures). If the STABILIZER switch is set to

• 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 thn
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

IIE/50/50E, REBEL 2000/300, IX, and D30, the Image
Stabilizer will not work during self-timer operation.
• 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.

7. Using the Tripod Mount
Adjusting the Revolving Mount
You can loosen the orientation lock-knob on the tripod mount to allow it to rotate as needed to fit a
particular camera model for switching between vertical and horizontal positions.
Detaching
Use the following procedures to remove and attach the tripod mount.
Rotate the tripod mount and
align the mounting indicator
on the tripod mount with the
one on the lens.
Slide off the tripod collar
away from the rear of the
lens.
Loosen the orientation
locking knob.
If the foot of the tripod mount overlaps the switch, loosen the orientation locking knob on the tripod mount to
move the foot.

9. Filters
(Sold separately)
You can attach filters to the filter mounting thread
on the front of the lens.
• If you need a polarizing filter, use the Canon
Circular Polarizing Filter (77mm).
• To adjust the polarizing filter, first store the lens
hood.
The built-in lens hood can reduce unwanted
reflections and also protects the front of the lens
from rain, snow, dust, and other substances.
When using the hood, extend it outward from
end of the lens until it stops and then turn it in
the direction of the arrow. For storage, rverse
the procedure.

EOS-1D, EOS-1V/HS, EOS-3 camera, autofocusing with the center focusing point is possible.
• Only one Extender can be attached to the lens and camera.
• If you use an Extender on the lens mounted on a EOS A2/A2E/5, set the exposure
compensation to -1/2 stop for the EF1.4X II or -1 stop for the EF2X II.
• Autofocusing is still enabled with Extender EF1.4X II attached.
• When an Extender is attached, the AF speed will become slower by design to retain proper
AF control.
