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

regardless of the focus mode.  
• If the contacts get soiled or have fingerprints on  
them, clean them with a soft cloth.

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 function may introduce errors.

With Extender EF2X II attached to the lens, the  
Image Stabilizer will work with the following cameras:  
ES-1Ds Mark III, EOS-1Ds Mark II, EOS-1Ds,

• 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  
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.  
• 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.

8. Hood  
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.

camera in the reverse order. If you attah the lthe camera first, misoperation may  
occur.  
With Extender EF2X II attached to the lens, onmanual focus is possible. However, with the EOS-  
1Ds Mark III, EOS-1Ds Mark ll, EOS-1Ds, EOS-1D Mark lll, EOS-1D Mark ll N, EOS-1D Mark ll,  
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.
