1. Mounting and Detaching the Lens

See your camera’s instructions for details on 

mounting and detaching the lens.

The lens mount has a rubber ring for enhanced 
dust- and water-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.

Attaching the strap

Thread the end of the strap through the strap 
mount on the lens and then back through the 
clasp on the strap. Pull the strap tight and check 
that there is no slack in the clasp.

After detaching the lens, place the lens with 
the rear end up to prevent the lens surface and 
contacts from getting scratched.

O

O

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. 

O

O

If the contacts get soiled or have fingerprints on 
them, clean them with a soft cloth.

O

O

If you remove the lens, cover it with the dust cap. 
To attach it properly, align the lens mount index 
and the 

 index of the dust cap as shown in 

the diagram, and turn clockwise. To remove it, 
reverse the order.
