B + W 82mm XS-Pro MRC NANO Clear #007 Filter - Plastic Storage Case - B + W Warranty.A B + W 82mm 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.

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.The reputation of B + W's Schott glass is world renowned. 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. Schott Glass used in the manufacture of this filter is legendary and synonymous with the highest standards of filter production.In production, the filter glass is dropped into the empty filter ring from the rear and held in place with a threaded retaining ring; this is a definite advantage over a competitor who uses a spring clip to hold the glass in place. A threaded retaining ring will hold the glass firmly and securely in place to avoid the possibility of rattling and provide perfect paralleling and flatness to your front lens element for ideal optics. The part about additional filters not binding is due to the fact that brass is a very stable metal and does not contract or expand like alloy. Minimize

This filter fulfils the desire of many photographers for pure lens protection without a filter effect. Its only function is to keep dirt, sand, or splashes away from the front lens. The extremely clear special glass with high transmission is MRC-finished. This filter uses B+W's 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. MRC (Multi-Resistant Coating) 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.

B + W 72mm XS-Pro MRC Nano Kaeseman Polarizing Filter - Plastic Storage Case - B + W Warranty.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. If you're out walking on a lovely day - in the mountains or at the beach - and you want to get a fabulous shot of a cloud-filled sky or make the water seem more saturated, then a polarizer is the way to go. This filter is the best way to make the clouds stand out, increase or decrease the saturation of the ocean or increase or decrease the reflection off the water. 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. The vista will take on the appearance of an imminent, ominous storm. Along with a UV or Skylight Filter, a polarizing filter should be a part of everyone's gear bag. It can turn a run-of-the-mill image into a stunning, creative photo by increasing color saturation.
