B+W Filter Clear Filter 40.5mm XS-Pro MRC Nano

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.

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.

Besides the excellent F-Pro standard mount which is suitable for telephoto lenses up to the most common wide-angle focal lengths, B+W offers the very flat XS-Pro mount for super-wide-angle lenses. This eliminates vignetting. For even more extreme focal lengths there is the Oversized mount on which the fiter glass protrudes This filter series is also made of brass and comes in matte black to prevent reflections.
