Get an excellent circular polarizer filter with the B+W 58mm Kaesemann High Transmission Circular Polarizer MRC-Nano Filter. It helps reduce glares and reflections by filtering out polarized light. With lesser reflections from non-metallic surfaces, you will see increased saturation of skies and foliage in your pictures. The filter features Kaesemann foils that allows 99.5% light transmission and is placed between plano-parallel optical glass. Each glass surface in the filter has multiple layers of anti-reflective coating to prevent internal ghosting. The filter is protected with a multi-resistant coating and a nano-coating, which ensures easier care and maintenance. It even includes a thin brass filter ring that minimizes vignetting and also enhances durability.
