About B+W 67mm XS-Pro Clear With Multi-Resistant Coating

From the Manufacturer Lens Protection with No Effect on Image QualityThis filter fulfills the desire of many photographers for pure lens protection without any filter effect. Its only function is to keep dirt and moisture away from the front lens. Made from special, extremely clear optical glass, B+W Clear filters exhibit very high transmission values.MRC - A Special Scratch-Resistant, Water and Dirt Repelling Coating The left half of this filter has a traditional coating. The right half has MRC coating. The lens elements of high-quality lenses and the plano surfaces of filters require a perfect shape and smoothness to achieve the best optical quality. Dirt, greasy fingerprints, water marks and scratches reduce the image contrast and the sharpness, which can result in blooming at light sources and have an effect similar to a soft-focus lens. A clean front lens element and clean filter surfaces are therefore an absolute pre-requisite for demanding photographers. MRC coating causes the water to bead up and slide right off. The MRC coating is first and foremost a broadband anti-reflection coating. This means that its reflection-reducing effect, which is thus also a transmission-increasing effect, i.e. one which suppresses scattered light and ghost images and transmits more light, has a broadband action over the full spectrum. In contrast, the (almost always blue) single-layer coating only has a high effect in the medium wavelength range around yellow and yellow-green where the eye is most sensitive to light, while its effect is greatly reduced toward the blue-violet and purple-red end regions of the visible spectrum. With the MRC coating, this blue, violet and red to deep-red light cannot produce any contrast reducing scattered light, spotty reflections or ghost images. A broadband effect can only be achieved with a multilayer coating which requires a much higher effort and precision because unevenness and irregularities of the individual layers build up on one another and amplify one another. Schneider therefore uses a plasma-assisted evaporation coating process in which inert gas ions accelerated in an electrical field compact the material deposited on the lens surface in the vacuum chamber. For photographers, the main advantage of MRC coating, is it's ability to combat flare and ghosting. An added benefit is that their filters remain free of dirt longer, so that they do not have to be cleaned so often. When cleaning the filter does become necessary, it is a lot easier to wipe off the dirt with a blower brush, because of MRC's ability to repel dirt and moisture. This also reduces the risk of micro-scratches which can occur during cleaning. Side view of XS-Pro DigitalMount. Click for larger view. XS-Pro Digital Filter MountThis filter uses our 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. Product Description Good lenses are far more expensive than filters; therefore, it makes good sense to attach a filter to protect the lens’ sensitive front element. In order for this lens protection not to add a permanent filter effect, the protective filter should consist of clear, completely colorless glass with the highest possible transparency. These are the precise characteristics of the B+W Clear (007M) Filter. The extremely hard MRC coating, capable of repelling both water and dirt, assists in lens protection, as well as, in the cleanup of the accidental fingerprint or occasional surface dust. This is extremely important with digital cameras, whose picture quality is much more sensitive to dirt.
