B+W MRC Multi Coated Filters
The B+W Filters MRC (Multi Resistant Coating) technology  is not only an enhanced process that assures virtually complete elimination of surface reflections on both sides of each B+W  filter and thus leads to a maximization of light transmission. In addition, its extraordinary hardness minimizes scratching and its water- and dirt repelling surfaces facilitate the care of  B+W filters. The MRC Coating transmits 99.5%
 

We source our Filters from Schneider Optics USA. B+W film and digital camera filters purchased from us are backed by us and Schneider U.S.A. We never sell gray market camera  filters.
