PM 58mm Professional Lens Cap

This fits perfectly on my 58mm filter thread and snaps on securely without feeling like it'll pop off. The grip is just right for compressing it to remove quickly, which is nice when I'm switching lenses in a hurry.

The squeeze-to-compress design makes it so much easier to pop on and off than the standard pinch-style caps I've used before. Works perfectly with the UV filter I have threaded on, and it feels secure without being too tight.

The inner squeeze mechanism is way more secure than the flimsy pinch-style caps I've had before, and it fits my 58mm filter threads without any wiggle. My lens has survived a few careless tosses into my bag since this arrived, still no dust or scratches.
