This B+W 46mm XS-Pro UV MRC-Nano 010M Filter blocks the invisible UV component of light from the sky, which can cause blur and to which many colour films react with a blue cast. This B+W UV filter is ideal for photography in high altitudes (in the mountains), by the sea and in regions with very clean air. The pictures gain brilliance and disturbing blue casts are avoided. Because the glass used in the B+W XS-Pro UV is colourless, colour rendition is not altered, aside from the elimination of the unwanted blue cast, and no increase in exposure is required. That makes this UV filter very suitable as protection of the front element of the taking lens against dust, flying sand, sea water spray and the like, and it can be kept on the lens at all times. It is recommended for analog colour and black-and-white as well as digital photography.
The B+W XS-Pro UV MRC-Nano 010M Filter employs 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. This filter has a front thread for mounting additional accessories such as filters, screw on shades and lens covers. XS-Pro filter rings are made of brass and are matt black to prevent reflections.
Schneider’s Proprietary MRC Coating
MRC refers to the unique Multi Resistant Coating developed by Schneider-Kreuznach, which comes as standard on this B+W XS-Pro UV filters. It provides perfect anti-reflection, brilliant colours 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.
Multi-Resistant Coating (MRC) with Nano Technology
The nano coating is an outer layer of protection that comes standard with this XS-Pro UV filter. The nanotechnology based characteristic (lotus effect) produces a better beading effect with water making the cleaning of this filter even simpler and faster than ever before. MRC nano has an improved outer (8th) layer over regular MRC.
