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. The hydrophobic coating reduces the adhesion of particles and water drops. The advantages are easy cleaning and maximum refl ection reduction. Also available for super-wide-angle lenses.
Multi Resistant Coating (MRC)
Quality begins in front of the lens, and that is, of course, where the filter is placed. MRC (Multi Resistant Coating) have a multicoating layer on both sides (7 + 1 on each) which ensures maximum reflection reduction and thereby eliminates disruptive stray light. In this way, more brilliant colors and higher contrasts can be attained. Due to the low residual refl ection (0.5%) MRC reliably prevents ghost or multiple images which can be caused by back reflection from the image sensor. Furthermore, MRC protects the filter from scratching with increased layer hardness, thereby preserving the high optical quality. In addition, MRC is dirt and water repellent, which makes cleaning easier.
For more than 90 years, B+W filters have been synonymous with quality and innovation. B+W has succeeded in establishing itself as one of the world‘s leading filter manufacturers. It has, for example, made decisive progress in surface coating. B+W is the first filter manufacturer in the world to offer MRC (Multi Resistant Coating). MRC nano coating is the most innovative development in thin-layer technology. The world-famous Käsemann type polarizing filter with its outstanding quality has been produced by B+W since 1989.
