B+W 55mm XS-Pro Digital Vario ND with Multi-Resistant Nano Coating

• Neutral Density Variable Filter allows photographer to set the density between +1 and +5 stops. XS-Pro Vario ND mount is an extra-wide design and should avoid vignetting concerns with most 17mm lenses on a full body frame.
• Multi-Resistant Coating (MRC) with Nano Technology with XS-Pro mount and brass ring construction
• May be combined with additional B+W ND Filters of fixed value for higher density choices (ND Vario should be used the as the outermost filter when combined)
• B+W ND Vario filter can be adapted to your individual requirements

The B+W 55 mm 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. By slowing your exposure time or increasing your aperture, you are able to control depth of field and convey movement more easily. For easier, repeatable control over density settings, the front ring is also visually demarcated with dots that represent different density values.
