Canon E-72II Lens Cap

The clip mechanism snaps on and off with a satisfying click, yet stays tight enough that I’m not worried about it popping off in my camera bag. I’ve knocked my lens against a door frame twice this week, and the cap took the scuffs—lens is still spotless.

Fits snugly on my lens and the spring-loaded center makes it quick to pop on and off. Exactly what I needed to keep dust off when the camera's in my bag.

I always forget to put the cap back on, but the spring-loaded clasp on this one makes it so easy to snap on one-handed. It’s also nice that the inner ridge fits the lens threads perfectly without any wobble.
