Get the perfect circular polarizer filter that professional photographers rave about with the B+W 122mm Kaesemann High Transmission Circular Polarizer MRC Filter. It helps to reduce glares and reflections by filtering out polarized light. As a result, there is an increase in saturation and color tonality, making your photos richer and vibrant. The filter utilizes Kaesemann foils that allow for 99.5% light transmission. These foils are placed between plano-parallel optical glass layers. Each glass surface of the filter features multiple layers of anti-reflective coating to eliminate internal ghosting. The 122mm filter features an F-Pro brass ring filter that does not bind to the aluminum housing of the lens, and minimizes vignetting and enhances durability.
