Tamron Front lens cap MkII 67mm

The spring-loaded center pinch mechanism makes swapping lenses so much quicker than the old screw-on caps. It snaps right onto my 67mm filter thread and hasn't budged once during a day of hiking.

I was worried it might not fit snugly, but the spring-loaded pinch grips my 67mm filter thread securely. Much easier to pop on and off than the old screw-in style I was using before.

The center-pinch mechanism feels precise, and it clicks on without any wobble. My 67mm lens is finally safe from dust, though I wish the cap had a slightly deeper grip for fumbling fingers.
