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.

 

After detaching the lens, place the lens with 

the rear end up to prevent the lens surface and 
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 

 index of the dust cap as shown 

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

Please be careful when laying the lens 
sideways. The lens may roll and fall, resulting 
in injury.
