Nikon LF-4 Rear Lens Cap

The hard plastic feels really solid and the bayonet mount clicks into place with a satisfying snap. I've had cheap caps crack on me before, but this one seems built to last.

Fits my 52mm lenses perfectly and locks on with a satisfying click, so I never worry about it popping off in my camera bag. The hard plastic feels solid enough to protect the rear element from dust and knocks.

Snapped this on right out of the box and it clicks into place with a satisfying, secure fit that I trust for tossing in my bag. The hard plastic feels dense enough to protect the mount without adding bulk, and it's kept the rear element dust-free on two shoots already.
