B+W 49mm Kaeseman Circular Polarizing Multi-Resistant Coating (MRC) Glass Filter (Slim)

The B&W 49mm Kaeseman Circular Polarizing Multi-Resistant Coating (MRC) Glass Filter (Slim) is constructed from select polarizer foils and especially prepared optical glass. Kaeseman ("encased") filters are completely edge-sealed for maximum durability under extreme climatic conditions.

Polarizing filters are used to select which light rays enter your camera lens. They can remove unwanted reflections from non-metallic surfaces such as water or glass and also saturate colors providing better contrast.
