キヤノン E-58 スナップオン 58mm レンズキャップ

Fits my 58mm lenses perfectly — the snap-on mechanism is secure but not too stiff. Much better than the cheap pinch-style caps I've been using.

Finally a lens cap that actually snaps on securely without that annoying wobble. The spring-loaded center mechanism grips firmly every time, and it's thin enough to leave the hood attached.

I've gone through three of these in the last two years because I keep misplacing them, but they never fail to protect the glass when I actually remember to use them. The snap-on fit is snug enough that it doesn't wobble in my bag, yet pops off with a light pinch when I'm ready to shoot.
