The B+W 58mm 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 full 6-stop exposure reduction, it opens creative possibilities from silky long-exposure water shots to razor-thin depth of field — even in bright daylight.
Built on SCHOTT optical glass and finished with B+W’s exclusive MRC Nano broadband coating on both sides, this filter delivers uniform light transmission across the full spectrum with minimal reflection. The durable brass ring with enhanced top knurling ensures a secure, slip-free grip, while the slim profile maintains compatibility with wide-angle lenses from 17mm full-frame equivalent.
Key features
- 6-Stop Exposure Reduction (OD 1.8): Dramatically extends shutter speeds or widens apertures, ideal for motion blur, silky waterfalls, and subject isolation in bright conditions.
- MRC Nano Premium Coating (Both Sides): Multi-resistant broadband coating maximises light transmittance, minimises reflections, and repels water, oil, and dust for effortless cleaning.
- SCHOTT Optical Glass: Precision-ground German glass ensures colour neutrality and zero image distortion across the entire frame.
- Brass Ring with Enhanced Knurling: Corrosion-resistant brass mount with a redesigned grip pattern for confident, precise filter attachment and removal.
- Slim Wide-Angle Compatible Design: Low-profile ring eliminates vignetting on lenses as wide as 17mm full-frame equivalent.
- Plastic-Free Packaging: Eco-conscious packaging from B+W’s Master filter line, reducing environmental impact without compromising filter protection.

Frequently asked questions
How many stops does the B+W 58mm MRC Nano ND filter reduce exposure by?
The B+W 58mm MRC Nano Master #806 ND Filter has an optical density of 1.8, which reduces exposure by exactly 6 stops, giving you full creative control over shutter speed and depth of field in a wide range of lighting conditions.
Is this ND filter compatible with wide-angle lenses?
Yes. Thanks to its slim filter ring design, the B+W 58mm MRC Nano ND is compatible with wide-angle lenses down to the equivalent of a 17mm full-frame focal length, making it a versatile choice for landscape and architectural photographers.
What makes the MRC Nano coating better than a standard coating?
B+W's MRC Nano coating is a high-quality broadband multi-layer treatment applied to both sides of the SCHOTT optical glass. It increases scratch resistance, ensures uniform and enhanced light transmittance across the full spectrum, and provides a nano-level protective layer that repels water and grease — making the filter extremely easy to clean and long-lasting.
