Safety Precautions
Precautions to ensure that the camera is used
safely. Read these precautions thoroughly. Make
sure all details are observed in order to prevent
risks and injury to the user and other people.
Warning Details pertaining to risks that may
result in death or serious injury.
zDo not look directly at the sun or other strong
light sources through a lens. This may result in
loss of sight.
zDo 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.
zDo not leave a lens in the sun without the lens
cap attached. The lens may concentrate entering
sunlight and cause a malfunction or fire.
zWhere the lens is mounted on a camera, make
sure to properly support the lens. If you hold only
the camera, the lens may fall off the camera and
cause a malfunction or injury.
zBe sure to attach the included strap to the lens
when carrying a camera around with the lens
mounted on it. Using the strap for the camera may
allow the lens to fall off the camera and cause a
malfunction or injury.
Caution Details pertaining to risks that may
result in injury or damage to other
objects.
zDo not leave the product in places exposed to
extremely high or low temperatures. The product
may cause burns or injury when touched.
zDo not insert your hand or fingers into the
product. This may result in injury.
zAttach a tripod or monopod that is sufficiently
sturdy to the tripod mount on the lens.

ENG-3
Handling Precautions
zDo not leave the product in excessive heat such as
in a car in direct sunlight. High temperatures can
cause the product to malfunction.
zIf 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.
zThe lens interior may appear to waver, but this
does not indicate a defect or failure, and will not
cause any problems in use.
zIn order to optimize aperture control, there are
occasions in which the diaphragm blades will
move during zooming and focusing, even when
the aperture value is set for aperture priority AE or
manual exposure, etc.
zPlease also read any lens related handling
precautions listed in your camera’s instruction
manual.

1. Attaching and Detaching the Lens1. Attaching and Detaching the Lens
Attaching the Lens
Align the lens mount indexes of the lens and
camera, and turn the lens clockwise until you
hear a click.
Detaching the Lens
Turn the lens counterclockwise while pressing
the camera’s lens release button. Detach the
lens once it has stopped turning.
Please refer to the camera’s instructions for
details.
zSet the camera’s power switch to OFF when
attaching or detaching the lens.
zAfter detaching the lens, place the lens with the
rear end up and attach the dust cap to prevent
the lens surface and contacts from getting
scratched. Make sure the lens and dust cap
mount indexes are aligned when attaching the
dust cap.
zContacts that are scratched, soiled, or have
fingerprints on them may result in faulty
connections or corrosion, which may lead to
malfunctions. If the contacts get soiled, clean
them with a soft cloth.
zThe lens mount has a rubber ring to improve
dust-resistance and water-resistance
performance. This rubber ring may cause
friction marks to appear around the camera’s
lens mount, although this will have no effect on
usage.
zSince the lens is heavier than the camera, turn
the camera when attaching or detaching the
lens. Ensuring that the lens can rest safely on its
own is recommended, such as first mounting it
on a tripod.
zRubber rings can be replaced at a Canon
Service Center. (chargeable)

Focusing/Control ring
zThe lens’ focusing ring (focusing/control ring) is
electronic.
zWith a camera capable of electronic full-time
manual focus, manual focusing is possible while
the camera is operable. However, this requires a
change in camera settings.
zWhen AF operation is set to One-Shot AF,
manual focus is possible after autofocusing
has been completed by continuing to press the
shutter button halfway (electronic manual focus
function). However, this requires a change in
camera settings.
zWhen movie recording, the AF speed will be
slower than the still photo shooting mode. It is
possible to adjust the AF speed on the camera
by setting Movie Servo AF to [Enable].
Please refer to the camera’s instructions for
details.
