Promaster Rear Lens Cap - Canon RF

Finally, a rear cap that clicks on securely without that awkward wiggle — the RF mount fits my lens perfectly. It's nice to have that extra layer of protection against dust when swapping lenses in a dusty room.

Finally, a rear cap that clicks on snug without any wobble. The dust protection is exactly what I needed for my RF lenses sitting in the bag between shoots.

The cap snaps on with a satisfying click and holds tight enough that I don’t worry about it popping off in my bag. It’s a simple plastic piece, but it does exactly what it’s supposed to for keeping dust off the rear element.
