ProMaster Rear Lens Cap for Canon EF and EF-S Lenses

This ProMaster Canon EF rear lens cap covers the back of Canon EF and EF-S lenses, zooms and primes alike. It protects the rear element from dust, smudges and scratches while the lens sits in a bag or a drawer.

ProMaster sizes it for the Canon EF/EF-S bayonet, so the Canon EF rear lens cap goes on and comes off the same way as the cap that came with your lens. ProMaster lists it for both mounts, so it also works as an EF-S rear cap on the smaller EF-S lenses.

Put the cap on as soon as the lens comes off the camera, and wipe the inside of it now and then so it does not carry dust onto the glass. A Canon EF rear lens cap is small and light, so a spare can live in your bag for every lens you own, or replace one that went missing or cracked.

The Canon EF rear lens cap is for the back of the lens only: the filter end needs a front cap, and a camera body needs a body cap. If you are not sure which mount your lens uses, bring it to the store in Fullerton or ask us. See every camera accessory we carry.
