Designed to eliminate light distortion and flaring caused by UV rays, the 18-layer, high-transmission coating provides up to 99.5% light transmission with uniformity and consistency. Featuring a precise aluminum alloy frame, B270 professional-grade optical glass, an anti-smudge layer, a scratch-resistant coating, and 0.3% surface reflectivity, this MC UV filter works well for nature photographers shooting in naturally-lit scenes.
