With this Olympus POSR-EP10 UW Anti-Reflecting Ring, you can ensure that the writing on the front of your M. Zuiko ED 8mm f/1.8 Fisheye PRO Lens does not show up in your underwater photos or videos. The ring fits onto the front of the lens and blocks the aperture, focal length, and other writing from being reflected in the front element of your housing's lens port. It is compatible with the Olympus PPO-EP02 Port mounted on their PT-EP08, EP10, EP11, EP12, and EP13 Underwater Housings for digital cameras. Additionally, it works with Focus Gear PPZR-EP05.
