Handling Cautions
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 espechazardous.
OO Do not point lens or camera at the sun or
photogh itis is because the lens concentrates
te sun’s rn when the sun is outside the image
r when sting with backlight, which could cause
tion or fir
r it is attad to the camera or not, do not
the lens under the sun without the lens cap
ached. This is to prevent the lens from concentrating
tsun’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 Wthe 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.

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 beomes worn, it is replaceable by a
Canon ServicCenter at cost.

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 stabilizr is equally effective for hand-
held photophy and photography with a
mood. Image Stabilizer effect may be

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.
