This is the nice swing out polarizer filter. It has a clamp mount, it is ~43mm.

This one has a small ring of separation in the center along with a few small spots on the edges (see photos) that may soften your images slightly. Otherwise, the glass is clean and scratch free with no haze, fungus, nor other issues. The swing movement is smooth and the mount shows light wear.

The original box is included.
