Instruction  
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.  
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  
againsharmful interference in a residential installation. This  
uipment generates, uses and can radiate radio frequency  
ergy 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:  
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 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.

1. Mounting and Detaching the Lens  
2. Setting the Focus Mode  
See your camera’s instructions for details on  
mounting and detaching the lens.  
To shoot in autofocus (AF) mode, set the focus  
mode switch to AF.  
To use only manual focusing (MF), set the focus  
ode switch to MF, and focus by turning the  
focusing ring.  
¡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.  
¡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.  
¡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  
K
index of the dust cap as shown  
in the diagram, and turn clockwise. To remove it,  
reverse the order.

from rain, snow, and dust.  
Attach and align the hood to the hood mount on  
the front of the lens, and turn the hood as show
by the arrow to secure it.  
The hood can be reverse-mounted on the lens  
for storage.  
¡The front end of the lens rotates, so hold it when  
attaching the hood.  
¡Part of the picture may be blocked if the hood is  
not attached properly.  
¡When attaching or detaching the hood, grasp  
the base of the hood to turn it. To prevent  
deformation, do not grasp the rim of the hood to  
turn it.

5. Fixing the Zoom Ring  
The zoom ring can be fixed to keep the lens at the shortest point. This function is convenient for  
carrying a camera on a strap because it prevents the lens from extending.

7. 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-8  
Tips on Using the Image Stabilizer  
¡The Image Stabilizer cannot compensate  
for a blurred shot caused by a subject that  
moved.  
¡With the EOS-1V/HS, 3, 30/33/Elan7/7E,  
30V/33V/Elan7N/7NE, Elan ll/Elan ll  
E/50/50 E, 300/Rebel2000, IX, and D30,  
the Image Stabilizer will not work during  
self-timer operation.  
¡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  
power than normal shooting, so fewer  
shots can be taken if you use the  
function.  
¡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.  
¡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.  
¡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.
