  • Nano Coating Simplifies Cleaning Process
  • Rugged Brass Filter Ring

The B+W 49mm Kaesemann XS-Pro Circular Polarizer MRC Nano Filter helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface. This results in a noticeable increase in the saturation of skies and foliage, as well as clearer imagery when photographing in hazy conditions. A circular polarizer differs from a linear polarizer in that it supports full use of a camera's autofocus and auto exposure functions.

Kaesemann-type filters feature greater optical efficiency than regular polarizing foils and are more neutral in color. The polarizing foils are cemented between plano-parallel optical glass layers, which are then precision-polished to achieve the most accurate plano-parallel surface. This edge sealing protects the filter layers from humidity and are ideal for use with high-speed telephoto and apochromatic lenses.

The Multi-Resistant Coating (MRC) is both an anti-reflection coating as well as a protective surface. It helps to increase light transmission by reducing reflections, scattered light, and ghosting. Additionally, it offers greater protection to the filter substrate and stays cleaner for longer than uncoated filters. The Nano coating associated with XS-Pro filters incorporates an additional 8th layer over the regular MRC and results in a better beading effect with water for greater cleaning efficiency.

B+W filters are constructed from high quality Schott glass for increased optical clarity and color fidelity. This filter features the XS-Pro Digital mount which is specifically designed for DSLR use with wide angle and zoom lenses. The filter ring is made from brass for durability as well as jamming prevention.

Reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface.
Arrange and filter directionally polarized light perpendicularly to the reflected light allowing for the absorption of much of the light.
Lessens haze in distant landscapes and provides more saturated, vivid colors.
Strongest effect when used at a 90° from the sun.
Kaesemann polarizing foils provide highly neutral coloring and higher image quality than conventional polarizing foils.
Multi-Resistant Coating offers both protection to the glass and helps to improve light transmission and image quality.
Nano coating promotes a better beading effect with water for more efficient cleaning.
Constructed from high-quality Schott glass for optical clarity.
Brass filter ring helps to prevent jamming and provides additional strength.
This filter ring's outside diameter is slightly larger than the actual thread size, and because of this you may be unable to attach the lens manufacturer's bayonet-mounted lens hood to the lens while using this filter. This is dependent on your specific lens and how thick the front rim of the lens is; with thinner, low-profile lenses usually being affected more.

          I have several B&W filters and this one is certainly fitting with the quality I've come to expect from B&W. The filter works great with my Sony a6000.

              Got this for my Sony NEX 6 and using a 49mm filter with a 40.5-49mm step up adapter. It is robust and the rotation is smooth yet not too loose. This is really great. Picture quality is good. However I am yet to see the true potential of this filter. I will take a few more photos with it and probably will be able to see the real power of this filter

                  I got this filter at the same time as an SMC Pentax DA 15mm lens, sight unseen. The fiter fit the lens well but I couldn't extend the lens' built in hood with this filter in place. This was no problem for me as I have other Circular Polarizers ,Hoya HD2, which allow using the built in lens hood. The B+W one fit and cleared OK on my other 49mm thread
                  lenses without built in retractable lens hoods. This was the first time I have used this brand of filter and like its unique inner ring labels which are easier to spot this filter when it is in a filter wallet.

                          Just what a polarizer should be, solid build, thin and light. Great optical quality. It's on a pricy side, but it goes great with my collection of primes. I wouldn't leave home without it.
