キヤノン E-58 II 58mm レンズキャップ

Finally, a cap that clicks on securely without any worry of it popping off in my bag. The snug fit gives me real peace of mind when I toss my camera in my backpack.

Mine arrived with a snug but smooth fit over the 58mm thread, and the center pinch mechanism feels solid enough that it won’t pop off in my bag. Dust hasn’t stood a chance since I started using it.

Snapped this right onto my 58mm lens and it hasn't budged, even with the cap in my bag. The center pinch mechanism is much smoother than the cheap ones I've used before, and it keeps dust off the glass perfectly.
