The B+W 52mm XS-Pro Clear MRC-Nano 007 is a simple, clear filter designed for general protection for your lens. This optically clear filter does not affect the overall image quality while helping reduce dust, scratches, moisture, and other elements from damaging your lens.
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.
