B+W 58mm XS-Pro Digital AUC Circular Polarizing Filter

This B+W XS-Pro Digital AUC Circular Polarizing Filter are constructed from high quality Schott glass for increased optical clarity and color fidelity. This filter features the XS-Pro Digital mount which is specifically designed for DSLR use with wide angle and zoom lenses. The filter ring is made from brass for durability as well as jamming prevention.

The Multi-Resistant Coating (MRC) is both an anti-reflection coating as well as a protective surface. It helps to increase light transmission by reducing reflections, scattered light, and ghosting. Additionally, it offers greater protection to the filter substrate and stays cleaner for longer than uncoated filters. The Nano coating associated with XS-Pro filters incorporates an additional 8th layer over the regular MRC and results in a better beading effect with water for greater cleaning efficiency.

Kaesemann-type filters feature greater optical efficiency than regular polarizing foils and are more neutral in color. The polarizing foils are cemented between plano-parallel optical glass layers, which are then precision-polished to achieve the most accurate plano-parallel surface. This edge sealing protects the filter layers from humidity and are ideal for use with high-speed telephoto and apochromatic lenses.
