The Clear Protection MRC XS-Pro NANO filter is simply a lens protection without a filter effect. Its only (but very important) function is to keep dirt, sand and splashes away from the front lens elements. The hydrophobic coating reduces the adhesion of particles and water drops, making less need for cleaning.
The extremely hard MRC (Multi Resistant Coating) optimizes the protective effect and aids cleaning in case of accidental fingerprints or when the surface becomes heavily soiled. This type of filter has a multi coating layer on both sides (7 + 1 on each) which ensures maximum reflection reduction and eliminating unwanted stray light. The MRC coating also protects the filter from scratching with increased layer hardness so preserving the qulaity of the flter.
The XS-Pro Digital filter mount is an extremely narrow filter mount to help against vignetting and is ideal for demanding DSLR photography with short wide-angle zooms, beginning at 12mm (APS format). This mount has a small construction depth yet it is fully equipped with a front thread for further accessories such as lens hood or snap-in lens caps. This mount series is also made of brass and comes in matte black to prevent reflections.
