B+W Vario-Filter ND 52mm MRC XS-Pro Digital Nano

B+W XS-PRO DIGITAL ND VARIO FILTER MRC NANO

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.

B+W FILTER MOUNTS
Precision with no Rough Edges

An important element in a perfect B+W filter is a high-precision filter mount. It must be easy to hold, easy to screw on and off the lens, and fit exactly. The filter glass is perfectly plane and is screwed securely in place. It fits without play and tension. B+W filter mounts are closely toleranced and have very small dimensions. Even with the standard F-Pro mount on wide-angle lenses, photos without vignetting are possible.

B+W XS-Pro Digital Mount
The Premium Line - a Filter Range for Exacting Requirements

The B+W Premium Line XS-Pro Digital is the filter range with an extremely slim filter mount. XS-Pro Digital is ideal for the demanding DSLR photographer with typical wide-angle zoom lenses starting from 12 mm focal length with APS-C and 18 mm focal length with 35 mm full frame. A number of filter diameters are available that include mirrorless camera systems also.
Despite the low profile height of 3.2 mm for screw-on filters and 4.2 mm for rotatable polarisers, (in each case without mount thread), this ring is equipped with a full front thread for additional B+W accessories such as a lens hood or snap-on lens cover (snap cap).

With the exception of the ND-Vario, B+W XS-Pro filter mounts are precision-made of brass. Brass is well known for being dimensionally stable and robust, which guarantees that filter mounting will remain smooth and easy over the long term. The filter glass rests in the brass mount without any movement or strain, and is therefore exactly plane, the optimum condition, which guarantees the maximum imaging performance. The matte black hard-chrome plating prevents any possible effects from reflections at the mount. All B+W XS-Pro Digital brass mounts have a full front thread for additional accessories.

B+W COATING SYSTEMS
High-performance Photographic Filters

Quality begins in front of the lens, and as is generally known, that is where the filter is. A filter must not restrict the performance of the photographic lens. An important criteria for a perfect B+W filter is a high-quality coating, also known as an antireflection coating. With a B+W filter, such layers are evaporated by means of thin-layer technique, a quite complex coating process. The coating material consists of special substrates that are applied in one or more layers depending on the coating system.

B+W MRC NANO
Nanotechnology with Lotus Effect

Both sides of the B+W MRC nano coated filters feature the same high-quality MC layer with 7 layers that is used in the MRC coating. This ensures high transmittance and maximum elimination of reflections by minimising reflection losses. Because the normal 4% reflection losses at the surface of the glass are reduced to an average of well below 0.5% with an MC layer, brighter colors and higher contrasts can be achieved.

The MRC nano outer layer is an innovative extra layer that significantly outperforms the dirt- and water-repellent effect of the well-known B+W MRC coating.

Thanks to the nanotechnology-based surface property (lotus effect), dirt can hardly adhere. Water experiences a very efficient beading effect and virtually rolls off the surface of the glass. Cleaning the filter is incredibly easy and fast. In addition, the superhydrophobic surface reduces fogging. After moving from cold to warm surroundings, the condensation disappears from the surface of the filter glass within seconds.
