Canon Lens Cap E-72 II

The pinch mechanism clicks shut with a satisfying snap, and it's snug enough that I don't worry about it popping off in my bag. Been carrying my 72mm lens around for a week now and the cap hasn't budged, plus it keeps the glass dust-free even in my dusty car.

I was tired of finding dust on my lens whenever I pulled it out of my bag, and this cap snaps on securely enough that I don't worry about it popping off. The inner lining feels smooth enough to avoid scratching the glass, which is a nice touch for something this simple.

Fits perfectly on my 72mm lenses and snaps on with a satisfying click, so I don't worry about it falling off in my bag. The recessed center makes it easy to grip even with one hand.
