Details about B+W 77mm XS-Pro Kaesemann HTC Circular Polarizer KSM HTC CPL MRC Nano Filter

- Schneider B+W Polarizing filters increase color saturation & reduce reflections. The neutral gray color and plane parallel polarizer material guarantee optimal image results. High-quality optical glass ensures excellent pictorial quality.
 
- B+W Käsemann HTC (High Transmission Circular) Polarizing filters provide greater light transmission while delivering the hallmark characteristics of a fine B+W polarizing filter.
 
- Known for reflection reduction and improved color, polarizing filters are valued tools, especially for ever-changing outdoor environments. The trade off historically has been light loss. Use of standard polarizing filters comes with a loss of up to 2.5 f/stops of light transmitted, which can increase desired depth of field or shutter speed. However, the B+W next-generation HTC filters utilize a proprietary layer of specially selected, high-transmission polarizing foil, which reduces light loss to just 1-1.5 stops making them work much better in low light situations.
 
- In addition, the Premium XS-Pro mount Käsemanns utilize MRC nano coatings to produce a better beading effect with water that makes cleaning simpler and faster than ever before. It offers a front thread for additional accessories. The following are key features of this filter:
 

- 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 Mount - This filter uses 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.
