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.
z
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.
z
Rubber rings can be replaced at Canon Service
Center. (chargeable)
