This UV Filter blocks the invisible UV component of light from  the sky, which can cause blur and to which many color films  react with a blue cast.  UV Filters are 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 is colorless, color rendition is not altered,  aside from the elimination of the unwanted blue cast, and no  increase in exposure is required. That makes a 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 color and black-and-white as well as digital photography.

Multi-Resistant Coating (MRC) with Nano Technology

The Nano coating is an outer layer of protection that comes  standard with all XS-Pro Digital MRC filters. 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.

MRC by B+W is not only an extraordinarily effective multiple  layer coating, it is also harder than glass, so that it protects  filters from scratches (for instance when cleaning the filters),  and it is also water and dirt repellent, thus facilitating  filter maintenance.

XS-PRO  Digital Brass Mount

This filter uses the thin XS-Pro Digital mount which is  especially suited for DSLRs with wide angle and zoom lenses. It  has a front thread for additional accessories such as lens caps  or hoods. All XS-Pro Digital mounts are made of brass and are  matte black to prevent reflections.

Retaining ring holds the filter Firmly

A threaded  retaining ring will hold the glass firmly and securely in place  to avoid the possibility of rattling and provide perfect parallelity and flatness to your front lens element for ideal  optics. then it can prevent moisture and dust into the middle of  the filter and the lens.

Another  advantage of retaining from back is to prevent the retaining  ring from being accidentally loosened during the removal of an  additional filter or a lens hood that has been screwed in too  tightly.
