The B+W 52mm MRC Nano Master #810 ND Filter is a precision-engineered neutral density filter designed for photographers who demand total exposure control. Built with SCHOTT optical glass and an optical density of 3.0, it delivers a reliable 10-stop light reduction, empowering you to shoot long exposures, silky waterfalls, and creamy bokeh even in the brightest daylight conditions.
B+W raises the bar with exclusive MRC Nano multi-resistant coating applied to both sides of the filter glass, dramatically reducing reflections while maximising scratch resistance and ease of cleaning. The solid brass ring with redesigned top knurling ensures a firm, confident grip, while the slim-profile design keeps the filter fully compatible with wide-angle lenses as wide as a 17mm full-frame equivalent — all delivered in responsible, plastic-free packaging.
Key features
- 10-Stop Light Reduction: Optical density of 3.0 lets you dramatically slow shutter speeds to capture motion blur, smooth water, and long-exposure effects in any lighting.
- SCHOTT Optical Glass: Premium German glass ensures neutral colour rendition with no unwanted colour cast across the entire image area.
- MRC Nano Coating (Both Sides): Multi-resistant broadband coating maximises light transmission uniformly across the full spectrum while delivering superior scratch resistance and effortless cleaning.
- Brass Ring with Enhanced Top Knurling: Durable brass construction paired with redesigned knurling provides a secure, slip-free grip even when attaching or removing the filter in cold or wet conditions.
- Wide-Angle Compatible Slim Design: Low-profile ring eliminates vignetting on lenses as wide as 17mm full-frame equivalent, making it an ideal fit for landscape and architectural photographers.
- Eco-Friendly Plastic-Free Packaging: B+W's commitment to sustainability means your premium filter arrives in fully plastic-free packaging without compromising protection.

Frequently asked questions
How many stops of light does the B+W 52mm MRC Nano Master #810 ND Filter reduce?
This filter has an optical density of 3.0, which reduces exposure by exactly 10 stops, allowing you to use much slower shutter speeds or wider apertures in bright conditions.
Will this filter cause vignetting on my wide-angle lens?
No. The B+W Master #810 features a slim ring profile specifically designed to be compatible with wide-angle lenses down to a 17mm full-frame equivalent without causing vignetting.
What makes the MRC Nano coating better than a standard coating?
The MRC Nano coating is a high-quality broadband multi-resistant coating applied to both sides of the SCHOTT optical glass. It ensures uniform light transmittance across the full spectrum with minimal residual reflection, while also providing superior scratch resistance and making the filter exceptionally easy to clean for a longer service life.
