B+W 72mm S03 MRC Nano Coated Kaeseman CIRCULAR Polarizer Filter - XSDP Mount

The B+W 72mm XS-Pro Digital MRC Nano Kaeseman Circular Polarizing Filter is constructed from select polarizer foils and especially prepared optical glass. Kaeseman (encased) filters are completely edge-sealed for maximum durability under extreme climatic conditions. - XS-Pro filters are extra thin for use with ultra wide angle lenses yet they retain their front threads. B+W's MC Nano coating takes filter production to a new level. It features 7-layers of anti-reflection coating as well as improved cleaning capabilities. Water droplets will bead up better and be easier to remove from the filter. This filter is also scratch-resistant. - Polarizing filters are used to select which light rays enter your camera lens. They can remove unwanted reflections from non-metallic surfaces such as water or glass and also saturate colors providing better contrast. The effect can be seen through the viewfinder and varied by rotating the filter. The filter factor varies according to how the filter is rotated and its orientation to the sun. - You can also use this filter when shooting into glass or windows since it will again either increase or decrease reflections. - If you're shooting black and white and want to simulate a threatening storm try throwing on a #25 Red filter. Along with a UV or Skylight Filter a polarizing filter should be a part of everyone's gear bag. - The high production standards combined with a sturdy brass filter ring make B+W filters hard to beat. These filters have a heft to them that is impressive. They may feel heavier but the benefit is in the construction and results. Not only is the glass exceptional but so is the seal between the ring and glass. The filter ring is made from brass yielding a stronger product. Brass filter rings are also less prone to jamming.
