Promaster 4536 49mm Lens Cap

Finally a lens cap that stays put even in a crowded bag—the precision molding makes it feel like it was made for my lens. The center-locking system gives just the right amount of resistance to know it’s secure, but still easy to pop off when I need to shoot.

The center-locking mechanism clicks into place so securely that I'm not worried about it popping off in my camera bag. It fits my 49mm lens perfectly with no wobble.

Finally found a lens cap that doesn't pop off in my bag—the center locking system gives a really secure fit. It's a bit snugger than my old cap, which is exactly what I wanted.
