B+W 72mm XS-Pro UV Nano MRC 010 Filter (66-1066124)

Although UV filters were designed originally for film cameras, this filter works great as a protective filter on any lens. With the advances of the digital age the sensors in many DSLRs are not susceptible to ultra violet rays, meaning they simply cannot see or interpret them. In this case the UV filtration effects of this filter are nullified and the filter then becomes a very high quality, high clarity, protection filter that will retain perfect image quality and crispness. This filter has a 99.8% light transmission rating, is made with high quality German Schott glass and is mounted in a brass ring. This filter will protect your lens from front element damage. Without a protective filter the damage could result in having to replace your expensive lens - wouldn’t you rather replace a filter instead of a lens?

This UV filter blocks the invisible ultra violet component of light from the sky, which can cause blur and to which many color films react to with a blue cast. These filters should be called UV-blocking filters because they are filters for technical applications that pass UV radiation and block all the other wavelengths. Nevertheless, the short term “UV filter” has become established among photographers.

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 the unwanted 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 for the front element against dust, flying sand, sea water spray and the like; additionally 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.

B+W 72mm XS-Pro High Transmission (HTC) Kaesemann MRC 2 Nano Circular Polarizer (66-1081477)

The new generation of Kaesemann High Transmission (HTC) polarizing filters is fitted with a new polarizing foil which has higher translucency (transmission), yet still provides outstanding effectiveness.

B+W Kaesemann Circular Polarizers are well suited for applications that require the highest possible imaging quality "Optical Flatness", especially with high-speed telephoto and apochromatic lenses.

The Kaesemann filters have a higher efficiency than conventional polarizing foils and they are cemented between high-grade plano-parallel optical glass. The resulting sandwich is then precision-polished again to achieve highly accurate plano-parallel surfaces. This is very important for use with telephoto lenses. The Kaesemann Circular Polarizers are then edge-sealed to protect the foil against humidity.

For this high-end polarizing filter, the foil pieces are selected individually for maximum color neutrality. Following cementing between high-grade optical glass, additional grading and polishing takes place. This guarantees outstanding sharpness even with very bright, apochromatic lenses. These latest cementing technique ensures lasting stability even in damp climates. The filter extension factor is only 2 to 3, equivalent to approximately 1 to 1.5 f-stops.

Both filters have the new nano coating which is an outer layer of protection that comes standard with all XS-Pro Digital nano 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. The MRC nano coating has an improved outer (8th) layer over regular MRC coatings.

These filters use the B+W XS-Pro Digital mount which is especially suited for DSLRs with wide angle and zoom lenses. The XS-Pro UV filter mount measures only 3.5mm in thickness, while the XS-Pro HTC CPL has a 5mm mount, and both filters still have front threads for additional accessories such as lens caps or hoods. Industry leading B+W uses only the highest quality German Schott glass for outstanding results every time. All XS-Pro Digital mounts are made of brass and are matte black to prevent reflections.
