Ideal lens protection made of optical glass, color-neutral. The MC8 coating features four layers on each side for high light transmission and maximum anti-reflection. The vapor deposition-based multi-layer coating ensures that both the front and back of the filter are coated, preventing 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 frame is made of black anodized metal, and the black-colored inner edges help avoid reflections. The edge sealing protects against dirt, and the frame maintains its shape despite temperature fluctuations.
