B+W XS-Pro 806 MRC Nano 39mm (1089217) 1.8 ND Filter
B+W XS-Pro 806 MRC Nano 39mm (1089217) 1.8 ND Filter are made with excellent, finely cut and polished special glass. The ND filter effect has been improved thanks to a combination of three different coatings achieved using a specially developed thin-film technology. To prevent distracting reflections, the coating includes a multi-layer anti-reflective part with seven layers on each side of the filter.
- Constructed from Schott glass for optical clarity.
- Thin brass filter ring helps to prevent vignetting, jamming, and provides additional strength.
- Plastic case included for storage and transport.
Solid Neutral Density 1.8 Filter is an ND filter with a 64x filter factor that provides a 6-stop exposure reduction. Its 1.8 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required. By slowing your exposure time or increasing your aperture, you are able to control depth of field and convey movement more easily. Neutral density filters do not affect the coloration of the image and are ideal for pairing with other filters.To prevent internal ghosting and reflections, each glass surface includes multiple layers of anti-reflection coating. This Multi-Resistant Coating (MRC) also offers greater protection to the filter substrate and helps it to stay clean for longer than with uncoated filters. The Nano coating associated with XS-Pro filters provides an additional eighth layer over the MRC, resulting in an improved beading effect when in contact with water for greater cleaning efficiency.
