72mm XS-Pro ND Vario MRC nano
Neutral Density Filter to reduce lightDue to it's adjustable density control, the B+W ND Vario filter can be adapted to your individual requirements. The XS-Pro mount offers an index setting, allowing the photographer to set the density between +1 and +5 stops. You may combine additional B+W ND filters of fixed value to achieve higher density choices. The ND Vario should be the outermost filter when combined with additional filters. The XS-Pro Vario ND mount is an EW (extra-wide) design, and should avoid vignetting concerns with most 17mm lenses on a full frame body.
Featuring 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.
This filter uses the 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.
