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 provides an additional eighth layer over the MRC, resulting in an improved beading effect when in contact with water for greater cleaning efficiency.
B+W filters are constructed from Schott glass for increased optical clarity and color fidelity. This filter features a thin mount which helps to reduce the likelihood to vignetting when used with wide-angle lenses. The filter ring is made from brass for durability as well as jamming prevention.
