The B+W 77mm MRC Nano Master #806 ND Filter is a premium neutral density filter engineered for photographers who demand precise exposure control. With an optical density of 1.8 and a 6-stop exposure reduction, it empowers you to shoot wide open in bright conditions, achieve silky motion blur in waterfalls, or create long-exposure cityscapes without compromise.
Built on SCHOTT optical glass and finished with B+W’s exclusive MRC Nano multi-resistant coating applied to both sides, this filter delivers exceptional light transmission uniformity across the full spectrum while offering outstanding scratch resistance and effortless cleaning — making it a long-lasting tool for serious image-makers.
Key features
- 6-Stop Exposure Reduction (OD 1.8): Dramatically slows shutter speeds to capture motion blur, smooth water, or shoot at wide apertures in harsh daylight.
- SCHOTT Optical Glass: Precision-grade German glass ensures colour neutrality and sharpness with zero unwanted colour cast across the entire image area.
- MRC Nano Coating (Both Sides): Broadband multi-resistant coating minimises reflections, increases transmittance uniformity, and provides a nano-layer that repels dust, water, and fingerprints.
- Brass Ring with Enhanced Top Knurling: The redesigned brass filter ring offers a secure, slip-free grip for easy attachment and removal, even in cold or wet conditions.
- Wide-Angle Compatible Slim Ring: The low-profile slim ring design prevents vignetting on lenses as wide as a 17mm full-frame equivalent.
- Plastic-Free Packaging: Eco-conscious packaging reflects B+W’s commitment to sustainability without compromising product protection.

Frequently asked questions
How many stops does the B+W 77mm MRC Nano Master #806 ND Filter reduce exposure by?
The B+W 77mm MRC Nano Master #806 ND Filter has an optical density of 1.8, which reduces exposure by 6 stops, giving you significant control over shutter speed and depth of field in bright lighting conditions.
Will this ND filter cause vignetting on wide-angle lenses?
No. The filter features a slim ring design that is compatible with wide-angle lenses equivalent to as wide as 17mm on a full-frame camera, making it suitable for landscape and architectural photography without darkened corners.
What makes the MRC Nano coating on this B+W filter special?
The MRC Nano (Multi-Resistant Coating) is a high-quality broadband coating applied to both sides of the SCHOTT optical glass. It maximises light transmittance uniformity, minimises residual reflections, and adds a nano-protective layer that increases scratch resistance and makes the filter extremely easy to clean.
