ニコン LC-52 52mm スナップオン レンズキャップ

I’ve been using this snap-on cap for a few weeks and the spring ring holds securely even when I toss my camera bag around. The 52mm size fits my lens perfectly without any wobble.

Snapped it on my 52mm lens and it fit perfectly on the first try, no fiddling or forcing needed. The spring retainer ring holds it securely enough that I don't worry about it popping off in my bag, yet it's still easy to pop off with one hand.

Finally found a lens cap that actually stays on. The snap-on spring retainer ring gives a satisfying, solid click that makes me feel confident it won't pop off in my bag.
