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  
againharmful interference in a residential installation. This  
ipmnt generates, uses and can radiate radio frequency  
eergy 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 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.  
Do not stand on the lens case. Falling off the case  
could result in injury.  
Do not stack lens cases. A falling lens case could  
cause an injury.  
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.  
• 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.  
• 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 Class B digital apparatus complies with Canadian ICES-003.

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.  
Attaching the strap  
• 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  
Thread the end of the strap through the strap

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.  
You can set the focusing distance range at  
m/19.7ft. to infinity, 6m/19.7ft. - 20m/65.6ft., or  
20m/65.6ft. to infinity.  
By setting the suitable focusing distance range,  
the actual autofocusing time can be shorter.  
After autofocusing in ONE SHOT AF mode, focus  
manually by pressing the shutter button halfway

9. Tips on Using the Image Stabilizer  
The image stabilizer in this lens is effective for hand-held shots or when using a monopod under the  
following conditions.  
MODE 1  
MODE 2  
• In moderately dark areas such as evening  
scenes.  
• When panning subjects in motion.  
• In locations where flash photography is  
prohibited such as live performances in  
theaters.  
• In situations where your footing is uncertain.  
• In situations where fast shutter settings cannot  
be used.  
ENG-10  
 
Tips on Using the Image Stabilizer  
• The Image Stabilizer cannot compensate for a  
blurred shot caused by a subject that moved.  
• Using a tripod also stabilizes the image.  
However, depending on the kind of tripod and  
shooting conditions, sometimes it may be better  
to turn off the Image Stabilizer function.  
• The stabilizer is equally effective for hand-held  
photography and photography with a monopod.  
• 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 powe
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

II/ELAN II E/50/50E, REBEL2000/300, IX, and  
D30, the Image Stabilizer will not work during  
self-timer operation.  
The image stabilizer function also operates when the  
lens is used with an Extension Tube EF12 ll or EF25 ll.  
• With Extender EF1.4X II/EF2X II attached to the  
lens, the Image Stabilizer will work with the  
following cameras:
