Thanks to its variable density, the first B+W Vario ND filter can be adjusted exactly to meet individual requirements. To this end, it comes with a continuous setting function with which the photographer can determine the required density reduction between +1 and +5 f-stops. To prevent aberrations, the light reduction cannot be set beyond a critical level. The XS-Pro Digital ND Vario MRC nano thus guarantees professional image results, even with high filter factors.
The newly developed Vario ND filter can be adapted to a wide range of subject situations and photographic requirements. Sometimes large apertures are needed in bright ambient light in order to separate a model optically from the background. Using several minutes of exposure time, architectural photographers can make people passing through the work space “invisible”. In landscape photography, flowing water or the surface of the sea can be made to appear fluffy and soft like cotton candy.

The MRC nano coating – all XS-Pro Digital filters have it. The outer layer of MRC nano has been strengthened in its effectiveness. The nanotechnology-based characteristic (lotus effect) produces a better beading effect in water. This makes cleaning the filter surface even simpler and faster. The hydrophobic surface reduces fogging. During the transition from a cold to a warm environment the fogging on the filter glass surface dissipates within a very short time.
