See your camera’s instructions for details on
mounting and detaching the lens.
After detaching the lens, put it down with the
contacts upwards, to avoid damaging the
contacts or lens surface.
If the contacts are dirty, scratched, or soiled with
fingerprints, etc., corrosion or a faulty
connection or operation may result.
Always attach the dust cap to the lens whenever it
is not mounted on the camera.To attach the dust
cap, align the mark on the dust cap with the mark
on the lens and turn the dust cap clockwise.To
remove the dust cap, turn it counterclockwise.
1. Mounting and Detaching the Lens
The lens mount has a rubber ring for enhanced
water- and dust-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.
