The B+W 72mm MRC Nano Master #810 ND Filter is a premium neutral density filter engineered for photographers who demand precise exposure control without any compromise in image quality. Built on SCHOTT optical glass and wrapped in a durable brass ring, this filter delivers a full 10-stop exposure reduction at an optical density of 3.0, giving you the creative freedom to shoot long exposures and wide apertures even in bright daylight.
B+W’s exclusive MRC Nano coating, applied to both sides of the filter, ensures minimal reflections, outstanding scratch resistance, and effortless cleaning — making this a professional-grade tool built for long-term use. Its slim ring design maintains full compatibility with wide-angle lenses down to the equivalent of a 17mm full-frame focal length, and the redesigned top knurling provides a confident, secure grip for easy mounting and removal.
Key features
- 10-Stop Exposure Reduction (OD 3.0): Dramatically extends shutter speeds to capture silky waterfalls, light trails, and creamy motion blur even under bright conditions.
- SCHOTT Optical Glass: Precision-ground glass from the world-renowned SCHOTT manufacturer guarantees colour neutrality and optical clarity with zero unwanted cast.
- MRC Nano Dual-Side Coating: Broadband multi-resistant coating on both surfaces minimises reflections, repels water and grease, and dramatically extends filter lifespan.
- Brass Ring with Enhanced Knurling: A robust brass filter ring resists warping and thread seizure, while the redesigned top knurling ensures a firm, slip-free grip during mounting.
- Wide-Angle Compatible Slim Design: The slim-profile ring eliminates vignetting on wide-angle lenses equivalent to a 17mm full-frame focal length.
- Plastic-Free Packaging: Environmentally responsible packaging reflects B+W’s commitment to sustainability without compromising product protection.

Frequently asked questions
How many stops of light does the B+W 72mm MRC Nano Master #810 ND filter reduce?
This filter has an optical density of 3.0, which reduces exposure by exactly 10 stops. This allows you to use much slower shutter speeds or wider apertures than would otherwise be possible in bright light.
Will this filter cause vignetting on wide-angle lenses?
No. The B+W 72mm ND features a slim filter ring specifically designed to be compatible with wide-angle lenses up to the equivalent of a 17mm full-frame lens, preventing vignetting at the corners of the frame.
What makes the MRC Nano coating on this filter different from a standard coating?
B+W's MRC Nano is a high-quality broadband coating applied to both sides of the SCHOTT optical glass. It maximises light transmittance uniformly across the entire spectrum, minimises residual reflections, and adds a nano-level protective layer that makes the filter highly scratch-resistant and very easy to clean.
