Filter B+W XS-Pro MRC Clear 007M 62mm

Lens protection without affecting image quality
This filter fulfills the desire of many photographers to ensure complete lens protection without any filter effect. Its only function is to protect the front lens from dirt and moisture. Made of special, ultra-clear optical glass, B+W Clear filters have a very high transmission value.

MRC - special, scratch-resistant, water and dirt-repellent coating

The left side of this filter has a traditional coating. The right side has a MRC coating.

High-quality lens elements and flat filter surfaces require perfect shape and smoothness to achieve the best optical quality. Dirt, greasy fingerprints, watermarks and scratches reduce image contrast and sharpness, causing light sources to bloom and have an effect similar to a soft-focus lens. Therefore, a clean front lens element and clean filter surfaces are an absolute must for the most demanding photographers.

The MRC coating causes water to bead up and slide off immediately.

The MRC coating is primarily a broadband anti-reflective coating. This means that its reflection-reducing effect, which is also a transmission-enhancing effect, i.e. one that suppresses stray light and shadow images and lets more light through, operates in a broadband manner across the entire spectrum. In contrast, a (almost always blue) single-layer coating only has a significant effect in the mid-wavelength range around yellow and yellow-green, where akis is most sensitive to light, and its effect decreases significantly towards the blue-violet and purple-red end of the visible spectrum. With the MRC coating, this blue, violet and red to deep red light cannot create any contrast that reduces stray light, speckle reflections or ghosting. The broadband effect can only be achieved with a multilayer coating, which requires much greater effort and precision, since the irregularities and irregularities of the individual layers accumulate on top of each other and reinforce each other. Therefore, "Schneider" uses a plasma evaporation coating process, in which inert gas ions, accelerated in an electric field, densify the material deposited on the lens surface in a vacuum chamber.

For photographers, the main advantage of the MRC coating is its ability to combat flare and ghosting. An additional advantage is that its filters stay clean longer, so they don't need to be cleaned as often. Kai filters do need to be cleaned, and it's much easier to remove dirt with a blower brush, as MRC is able to repel dirt and moisture. This also reduces the risk of micro-scratches that can occur during cleaning.
