B+W F-Pro Mounts

These filters use the standard B+W F-Pro mount. The Clear Protective and UV filters are mounted in a 4.5mm mount and the Circular Polarizers are mounted in a 7mm mount. B+W filters are constructed from high quality Schott glass for increased optical clarity and color fidelity. They feature a brass filter ring for durability as well as jamming prevention both have front threads for additional accessories such as lens caps or hoods.

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.

B+W Filters are manufactured in Germany.
