The B+W 55mm XS-Pro Digital ND Vario MRC-Nano Filter offers adjustable density control and can be adapted to individual requirements with ease. The XS-Pro mount of the filter provides an index setting so that the photographer can set the density between +1 to +5 stops. It allows users to darken the image by reducing exposure so that they can use wider aperture settings or longer shutter speeds. The filter also features an MRC-nano coating to protect against the elements as well as offer anti-reflective properties to prevent internal ghosting. The nano coating is an external layer of protection that produces a better beading effect with water to make cleaning of the filter even simpler and quicker.
