1. Mounting and Detaching the Lens

See your camera's instructions for details on

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

K index of the dust cap as shown

index and the

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.
