See your camera’s instructions for details on
mounting and detaching the lens.
1. Mounting and Detaching the Lens
• After detaching the lens, place the lens with the
rear end up to prevent the lens surface and
electrical contacts from getting scratched.
• If the contacts get soiled, scratched, or have
fingerprints on them, corrosion or faulty
connections can result.The camera and lens may
not operate properly.
• If the contacts get soiled or have fingerprints on
them, clean them with a soft cloth.
• If you remove the lens, cover it with the dust cap.
To attach it properly, align the lens mount index
and the K index of the dust cap as shown in the
diagram, and turn clockwise.To remove it, reverse
the order.
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.
