Reduce reflections and glares with the help of the B+W 105mm Kaesemann High Transmission Circular Polarizer MRC Filter. It filters out light that has been polarized due to reflections from non-metallic surfaces. By filtering out polarized light, it provides a noticeable increase in saturation and clearer images when shooting in unfavorable conditions. The filter features Kaesemann foils that provide greater optical efficiency, and they are also neutral in color. These foils are cemented between layers of plano-parallel optical glass and precision-polished to get an accurate plano-parallel surface. The 105mm filter features an F-Pro brass filter ring, which do not bind to the aluminum housing of the lens, thereby preventing jamming and increases durability.
