Promaster 4550 55mm Lens Cap

Clips on firmly without feeling like it’s going to pop off, and the matte finish doesn’t attract smudges like my old cap did. Exactly what I needed for my 55mm lens.

Finally a cap that actually clips on securely instead of feeling like it'll fall off at the slightest bump. The spring-loaded mechanism is tight enough that I don't worry about it popping off in my bag.

Fits my 55mm lens like a glove and the pinch-release is smooth enough that I don't fumble when swapping lenses quickly. It's plastic but feels sturdy, so I'm not worried about it cracking in my camera bag.
