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.
●
Do not look directly at the sun or other strong light sources through
a lens. This may result in loss of sight.
●
Do not leave a lens in the sun without the lens cap attached. The
lens may concentrate entering sunlight and cause a malfunction or fire.
Caution
Details pertaining to risks that may result in injury or
damage to other objects.
●
Do not leave the product in places exposed to extremely high or low
temperatures. The product may cause burns or injury when touched.
●
This product emits low level magnetic flux. If you use an implantable
cardiac pacemaker or other medical device and feel abnormalities,
please keep away from this product and consult your doctor.
ENG-3
General Precautions
Handling Precautions
●
Do not leave the product in excessive heat such as in a car in direct
sunlight. High temperatures can cause the product to malfunction.
●
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.
●
When the lens is not attached to the camera or the power switch of the
camera is in the off status when the lens is attached, shaking the lens
may cause the internal lens group to shift and noise may occur, but this is
not a malfunction. Although the internal lens group shifts due to vibration
such as when the lens is carried, this will not affect aspects such as
performance.
●
In order to optimize aperture control, there are occasions in which the
aperture blades will move during focusing, even when the aperture value
is set for aperture-priority AE or manual exposure, etc.
●
Please also read any lens related handling precautions listed in your
camera’s instruction manual.
Shooting Precautions
●
Focus again after recovering from the auto power off status.
●
To maintain the focus position in the shooting-ready status, set [Auto
power off] to [Disable] on the camera.
●
After detaching the lens, or after trying to detach the battery from the
camera, focus the camera again. Due to the structure of the focus lens
drive mechanism, the focus lens may significantly shift from its original
position.

● Set the camera’s power switch to OFF when attaching or detaching the
lens.
● Attach the lens cap before detaching the lens from the camera.
● After 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.
● Contacts 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.
● The 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.
●Rubber rings can be replaced at Canon Service Center. (chargeable)
