B-AND-W UV filter 010 - MRC nano surface coating - XS-pro digital mount - 82 mm

B+W's filters are made with a socket made of a brass alloy with excellent physical characteristics and high-purity, distortion-free, thick Schott glass, with particularly precise workmanship, the most modern production technology, in accordance with the highest quality requirements. Finally, each type is provided with a different surface treatment, which completes the perfection of the B+W filters. From the raw materials used to the final touches, 100% "Made in Germany". B+W UV filters (factory code: 010) are primarily used to physically protect the front lens of the lens. They block the range of wavelengths of light smaller than 300 nm, and then, with an intense increase, an increasingly larger part is allowed through. From approx. 430 nm, reality is transmitted to the lens with absolutely minimal light loss (< 0.5%). In the case of digital machines (with the exception of very extreme situations), we do not notice any difference between the use of clear and the UV filter. In the case of negative films sensitive to UV radiation, the UV filter prevents the occasional blue shift and lightening, e.g. in high mountains, at sea, or in places with extremely clean air. This filter is equipped with eight layers of surface treatment (MRC) on both sides, which, among other things, ensure anti-reflection and dirt resistance. This filter is made with an F-pro mount, which is the B+W standard mount, which can also be used excellently on wide-angle lenses. It is also equipped with a front thread, so an additional filter (e.g. CPL) or an accessory can be connected, and lens caps with internal nails can be used.
