Neutral density camera filter B&W 802 Master, 52 mm, Multi Resistant Coating (MRC)

The B&W 802 Master neutral density camera filter, 52 mm with Multi Resistant Coating (MRC) reduces the amount of light entering the lens to enable longer exposures and wider apertures without overexposure. Made from finely ground and polished special optical glass, the filter maintains lens image quality while delivering uniform, color-neutral light attenuation across the visible spectrum. The thin-film coating combines a neutral density layer with a seven-layer anti-reflective system on each side and a final dirt- and water-repellent outer layer to minimize reflections and simplify cleaning and maintenance.

Advantages

The ND filter reduces light by two f-stops, allowing for selective depth-of-field control and extended shutter times while preserving color neutrality. The Multi Resistant Coating provides multi-layer anti-reflection protection plus an outer hydrophobic and oleophobic layer that resists dirt and eases cleaning. High-quality optical glass ensures minimal impact on resolution and sharpness, and the coating construction yields consistent attenuation across the visible range.

Suitable for

• Landscape photography that requires longer exposures to smooth water or cloud movement
• Portrait work where wider apertures are needed for subject separation
• Long exposure urban photography to capture light trails or reduce moving crowds
• Creative motion-blur and wipe effects

How to use

Screw the 52 mm B&W 802 Master ND filter onto a lens with a matching thread. Compose and meter as usual; the filter reduces incoming light by two f-stops so adjust aperture or shutter speed accordingly to achieve the desired exposure and creative effect. For selective focus, open to a wider aperture to reduce depth of field; for long exposures, use a tripod and extend shutter time to capture motion blur or smooth water. Clean the filter gently using a soft brush and microfiber cloth; the outer coating eases removal of fingerprints and dust.

Usage recommendations

Use the filter with a tripod for long exposures to avoid camera shake. When precise exposure is required, meter with the filter in place or apply the two-stop correction to your exposure settings. Store the filter in its protective case when not in use to preserve the coating and optical quality.
