B+W 49mm XS-Pro Digital ND Vario MRC-Nano Filter

B+W 49mm XS-Pro Digital ND Vario MRC-Nano FilterThe B+W 49mm XS Pro Digital ND Vario MRC Nano Filter is a solid variable neutral density filter providing an exposure reduction of 1 to 5 stops. The 0. 3 to 1. 5 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required. The degree of density is easily controlled by rotating the front filter ring, helping you to predetermine the additional exposure length required.
