Only a few years ago, photographers and video-users were asking for special effects filters. Nowadays, all over the world, they ask for Cokin filters.This Minolta Cokin 49mm filter kit includes UV and circular polarizer filters. UV filter absorbs ultra-violet rays, improves the clarity and reduces the haze. It also protects your valuable lens from dust, sands, water, etc... Circular polarizer removes unwanted reflections from non-metallic surfaces such as glass and water, and improves dramatically the color saturation of blue skies.
