Ideal lens protection made from optical glass, color neutral. The MC8 coating features four layers on each side for high light transmission and maximum anti-reflective properties with a vapor-deposited multi-coating. Both the front and back of the filter are coated to prevent loss of contrast and brilliance, as well as ghosting and double images. The ultra-thin wide-angle design prevents vignetting and can remain permanently on the lens without significantly extending the lens mount. A protected front lens saves costly repair expenses. The filter is made from optical glass, with a black anodized metal filter holder and black-coated inner edges to avoid reflections. The edge sealing protects against dirt, and the frame maintains its shape despite temperature fluctuations.
