B+W XS-PRO DIGITAL ND VARIO FILTER MRC NANODThe B+W ND-Vario filter can be adjusted exactly to the desired situation thanks to its infinitely variable density. It has an index setting that allows the photographer to determine the required density between +1 and +5 f-stops. To avoid imaging errors, the light reduction cannot be set above a critical value. The color reproduction remains constant over the entire setting range. The B+W ND vario filter thus achieves professional imaging performance even with high filter factors The effect of the B+W ND vario filter can be infinitely adjusted to the most diverse motif situations. Often a large aperture is desired in order to optically separate the main subject from the background, or deliberately long exposure times in order to make flowing water soft and fragrant. The B+W ND Vario Filter is ideal for DSLR video when a specific aperture is required.-B+W Premium Line: XS-PRO Digital B+W Coating: MRC nano.
