B + W 72mm XS-Pro Digital Nano MRC Clear #007 Filter -
A B + W 72mm XS-Pro Digital NANO Multi-Coated (MRC) Clear #007 Filter is for color as well as black and white photography. It also serves as a permanent lens protector. The value of a clear filter covering a lens has been well-documented over the years. How many stories have we all heard about photographers dropping lenses and smashing front elements? With a front lens protection filter on, the chances of preserving the valuable glass in your lens increases many fold. Shall we call it a form of inexpensive insurance.
B + W's Multi-Coated (MRC) coating takes filter production to a new level. It features improved cleaning capabilities. Water droplets will bead up better and be easier to remove from the filter. This filter is also scratch-resistant. Single coating is applied to one layer on each glass surface. This improves light transmission from about 92% (uncoated glass) to about 98%. It also has certain anti-reflective properties that help prevent against ghosting and internal flaring.
XS-Pro filters are extra thin but still retain front threads. The filter ring is made from brass yielding a stronger product. Brass filter rings are also less prone to jamming. In addition, the seal between the glass and filter ring is exceptionally strong giving the filter added strength and durability. The excellent Schott Glass used in the manufacturing of this filter is legendary and synonymous with the highest standards of filter production.
XS-Pro Extr a-Slim.
Provides extra-slim mounting rings that eliminate problems associated with SLR wide-angle and telephoto imaging. This mount is especially suited for DSLRs with wide angle lenses. This mount will avoid vignetting with most 17mm lenses on a full frame body. Some report success with lenses as wide as 16mm. 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. Only UV, Clear, and Käsemann Circular Polarizers are offered in this mount, with the latest MRC nano coating.
Always Shoot a test to confirm with your equipment.
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.
