 After detaching the lens, place the lens with the 

rear end up and attach the dust cap to prevent 

the lens surface and contacts from getting 

scratched. Make sure the lens and dust cap 

mount indexes are aligned when attaching the 

dust cap.

 

z

 Contacts that are scratched, soiled, or have 

fingerprints on them may result in faulty 

connections or corrosion, which may lead to 

malfunctions. If the contacts get soiled, clean 

them with a soft cloth.

 

z

 The lens mount has a rubber ring to improve 

dust-resistance and water-resistance 

performance. This rubber ring may cause 

friction marks to appear around the camera’s 

lens mount, although this will have no effect on 

usage.

 

z

Rubber rings can be replaced at Canon Service 

Center. (chargeable)
