Olympus POSR-EP05 Anti-Reflexion Ring for M.14-42 II & M.ZUIKO 45

Olympus POSR-EP05 UW Shading Ring

The POSR-EP05 Anti-Reflecting Ring for PT-EP06L, PT-EP06, and PT-EP05L underwater housings. This device blocks the writing, such as aperture and focal length, etc, on the front element of your lens from being reflected in the glass of your housing's lens port.
This will prevent the writing from showing up in your underwater photos and Videos.
