The B+W F Pro Filter Mounts are 4mm high and the B+W XS Pro Nano filters low profile are 3.5 mm high are prefect for any wide angle lens.
Both B+W mounts are solid brass made in Germany. All B+W filter optics are made with Schott Glass. The B+W brass mounts use the classic two part retaining ring method to hold the ground to be perfectly flat Schott Glass optical blanks with out stress.
The B+W UV Haze MRC 010M Filter or B+W Clear MRC 010M Filters are prefect for full time use, both are clear filters useful as protective filters. The additional benefit of the B+W UV 010 glass is the reduction of excess UV light, this benefit has the greatest effect on silver based film. The B+W Filters or any protective filter also helps to keep dust and moisture from reaching your cameras front lens element.

The Multi-Resistant Coating (MRC) is both an anti-reflection coating as well as a protective surface for the filter glass. It helps to increase light transmission by reducing reflections which cause lens flair. The new B+W MrC Nano XS Pro filters offers not only lens protection but are easier now to clean and they stay cleaner longer because of the top Nano coating from B+W better than any uncoated filter. The B+W XS Pro Nano's rated 5 stars on every site on the web. 2filter gives the Nano XS Pro 6 stars because no other camera filter we have seen is as good as the XS Pro's. NO B+W filters in Clears and Uv's are available without coatings every filter style of B+W UV 010's or B+W Clear 007's are made with Anti Reflective coatings.

All B+W camera filters are constructed using the highest quality Schott optical glass for absolute clarity and perfect neutral color.
