Variable Neutral Density 52mm MRC XS-Pro mount filter is made out of neutral gray Schott NG-glass. It blocks out the entire visible spectrum evenly and allows light reduction without influencing the colour rendition or contrast. This filter provides an exposure reduction of 1 to 5 stops.
The 0.3 to 1.5 density creates a darkening of the entire image; this allows you to photograph with a wider aperture or slower shutter speed than usually required. The degree of density is controlled easily by rotating the front filter ring. The extremely hard MRC (Multi Resistant Coating) optimizes the protective effect and facilitates cleaning in case of accidental fingerprints or when the surface becomes 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 and reserving the quality of the filter. An MRC filter is also dirt and water resistant which makes it extremely easy to clean.
The XS-Pro Digital filter mount is an extremely narrow filter mount 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.
