B+W XS-PRO Filters employ a newly developed mounting ring that is especially suited for SLRs with wide angle and zoom lenses. The extremely thin design prevents the mounting ring from vignetting in even the widest shots.
B+W XS-Pro Digital Filters have front threads for mounting additional accessories such as filters, screw on shades and lens covers. XS-Pro filter ring are made of brass and are matt black to prevent reflections.
MRC refers to the unique Multi Resistant Coating developed by Schneider-Kreuznach, which comes as standard on B+W XS-Pro Digital Filters. It provides perfect anti-reflection, brilliant colors and high contrast. Only Schneider lenses and B+W filters are protected by this extremely resistant multi-layer broadband coating (eight layers on both sides). In addition, the scratch-resistant, water- and dirt- repellent outer layer makes it easier to clean the glass surface. Due to its low residual reflection (0.5%) MRC prevents ghosting or double images, which can be caused by return reflections from sensors.
Ultraviolet light, which manifests itself in photographs as reduced clarity and the appearance of haze, is blocked by the UV 010. Ultraviolet light is invisible to the eye and is strong in mountainous and coastal areas with very clear air. This makes the colorless UV 010 an indispensable filter because it requires no exposure compensation.
