OKKO Magnetic Lens Caps 77mm

I used to lose lens caps every other shoot, but this magnetic one just snaps on and off without me even looking. The grip is firm enough that it hasn't popped off in my bag once, and swapping it mid-hike takes two seconds.

The magnetic attachment is strong enough that the cap stays put even when I toss the lens into my bag, and it pops off easily when I need to shoot. I don't miss fumbling with a traditional screw-on cap at all.

Took me about 2 seconds to realize this magnetic cap is a game-changer for quick lens changes in the field. The hold is strong enough that I’m not worried about it popping off in my bag, but it still comes off effortlessly when I need it.
