The POSR-EP10 Anti-Reflecting Ring for the M. Zuiko ED 8mm f1.8 Fisheye PRO Lens. Underwater light shield ring compatible with Focus Gear PPZR-EP05. 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.
