Overview
Minimize reflections and glares from polarized light with the B+W 43mm Kaesemann High Transmission Circular Polarizer MRC Filter. It helps to filter out light that becomes polarized due to it reflecting off non-metallic surfaces. When this polarized light is filtered out by the filter, you can see noticeable improvements in saturation and color tonality. The filter features the latest Kaesemann foils that offer greater optical efficiency, and they are neutral in color. These foils are cemented between layers of plano-parallel optical glass. The sandwiched layer of foils and glass surfaces are precision-polished to achieve a highly accurate plano-parallel surface, which is necessary for photography using telephoto lenses. Each glass surface of the filter has an anti-reflective coating to prevent internal ghosting and maintain optimal levels of color fidelity. The 43mm filter features an F-Pro brass ring design that prevents jamming and ensures better durability.
