Safety Precautions  
OO 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.  
OO 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.  
OO 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.  
OO Do not leave the lens in excessive heat such as in a car  
in direct sunlight. High temperatures can cause the  
lens to malfunction.  
OO When the lens is mounted on a camera, be sure to also  
hold the camera by the lens, including when mounting  
on a tripod. Only holding by the camera could result in  
scratches on the camera body or the lens itself. The lens  
may also detach from its mount and fall, causing injury.  
OO Do not use a strap attached to the camera. The mount  
may break, resulting in the lens falling off and causing  
injury or in scratches on the camera. Be sure to use the  
camera with a dedicated strap attached correctly to the  
strap mount on the lens.  
Conventions used in this instruction  
Warning to prevent lens or camera malfunction  
or damage.  
OO Do not stand on top of the lens case. You may fall and  
injure yourself.  
OO Do not pile lens cases on top of one another as they  
may fall and cause injury.

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  
dust- and water-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  
OOAfter detaching the lens, place the lens with  
the rear end up to prevent the lens surface and  
contacts from getting scratched.  
OOIf the contacts get soiled, scratched, or have  
fingerprints on them, corrosion or faulty  
connections can result. The camera and lens  
may not operate properly.  
OOIf the contacts get soiled or have fingerprints on  
them, clean them with a soft cloth.  
OOIf you remove the lens, cover it with the dust cap.  
To attach it properly, align the lens mount index  
and the index of the dust cap as shown in  
the diagram, and turn clockwise. To remove it,  
reverse the order.  
Thread the end of the strap through the strap  
mount on the lens and then back through the  
clasp on the strap. Pull the strap tight and check  
that there is no slack in the clasp.

This is a useful feature for changing focus when shooting movies.  
With the focus preset switch set to OFF, set the focus mode  
switch to PF.  
Rotate the playback ring to  
change the focus.  
When the playback ring is rotated in a certain direction, focus changes in the same direction as when  
the focusing ring is rotated.  
You can make a 2-step change in focus shift speed depending on the angle that the playback ring is  
rotated to.

OO MODE 1: Corrects vibrations in  
all directions. It is mainly effective  
for shooting still subjects.  
OOMODE 2: Corrects vertical  
camera shake during  
following shots in a horizontal  
direction, and corrects  
horizontal camera shake  
during following shots in a  
vertical direction.  
OO MODE 3: Corrects vibration only  
during exposure. During panning  
shots, corrects vibration during

The image stabilizer for this lens is effective for hand-held shots in the following conditions.  
O MODE 1  
O MODE 2  
ON  
ON  
OFF  
OFF  
OOIn semi-darkened areas such as indoors or  
outdoors at night.  
OOWhen panning subjects in motion.  
OOIn locations where flash photography is  
prohibited, such as art museums and theater  
stages.  
OOIn situations where your footing is uncertain.  
OOIn situations where fast shutter settings  
cannot be used.  
O MODE 3  
OOSince camera shake is stabilized only during  
exposure, following a subject is easier such as  
when shooting a fast and irregularly moving  
player during sports photography.  
ENG-12  
Tips on Using the Image Stabilizer  
OOThe Image Stabilizer cannot compensate for a  
blurred shot caused by a subject that moved.  
OOSet the STABILIZER switch to OFF when you  
are taking pictures using the Bulb setting (long  
exposures). If the STABILIZER switch is set to  
ON, the image stabilizer function may introduce  
errors.  
OOUsing 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.  
OOThe stabilizer is equally effective for hand-  
held photography and photography with a  
monopod. The Image Stabilizer effect may be  
reduced, however, depending on the shooting  
environment.  
OOThe Image Stabilizer might not be fully effective  
in the following cases:  
You shoot from a violently moving vehicle.  
You move the camera dramatically for a  
panning shot in Mode 1.  
OOThe Image Stabilizer consumes more power than  
normal shooting, so fewer shots can be taken if  
you use the function.  
OOThe 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.  
OOThe Image Stabilizer also operates when the  
lens is used with extension tube EF12 II or EF25  
II or the extender EF1.4× III or EF2× III.  
OODepending on the camera there may be image  
shake, such as after releasing the shutter.  
However, this does not affect shooting.  
OOIf 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.  
OOWith the EOS-1V/HS, 3, ELAN 7E/ELAN  
7/30/33, ELAN 7NE/ELAN 7N/30V/33V, ELAN II/  
ELAN II E/50/50E, REBEL 2000/300, IX, IX Lite/  
IX7, and D30, the Image Stabilizer will not work  
during self-timer operation.

9. Infinity Compensation  
Mark  
10. Hood  
Infinity compensation mark  
Distance index  
The special hoods that come with all these  
lenses cut out unwanted light and protect the  
front of the lens from rain, snow, and dust.  
To compensate for shifting of the infinity focus  
point that results from changes in temperature.  
The infinity position at normal temperature is the  
point at which the vertical line of the distance  
scale L mark is aligned with the distance index.  
To attach the hood, loosen the hood lock knob  
by turning it counterclockwise. Fit the hood onto  
the lens’s hood mount, and tighten the lock knob  
to fix it in place. Use the same procedure, in  
reverse, to remove the hood.  
For accurate focusing in MF on subjects at infinity  
distance, look through the viewfinder while rotating  
the focusing ring.

An attachment slot is provided for a wire-type  
security lock. The slot is located under the cover  
for the orientation locking knob.  
Replacing the Tripod Mount (EF400mm  
f/2.8L IS II USM only)  
Replacement with the included monopod mount  
can be done at a Canon Service Center at cost.  
Since the mount requires special fastening, as  
a safety precaution, do not replace the mount  
yourself.  
A wire-type security lock can be purchased  
separately.
