Neutral density camera filter B+W 806, 58 mm, Multi Resistant Coating (MRC)

The B+W 806 Master 58 mm neutral density (ND) filter with Multi Resistant Coating (MRC) reduces the amount of light entering the lens without changing the color balance. Made from finely ground and polished optical glass, this ND filter maintains high image quality and optical clarity. The thin-film coating system combines the neutral density effect with multi-layer anti-reflective layers and a dirt- and water-repellent outer layer to minimize reflections, ensure uniform light attenuation across the visible spectrum, and simplify cleaning and maintenance.

Advantages

The filter provides uniform and color-neutral light reduction so exposure control and creative effects can be achieved without introducing color cast. Multi-layer anti-reflective coatings on both sides reduce stray reflections and flare, while the hydrophobic and oleophobic outer layer resists dirt and moisture for easier cleaning. The optical glass base preserves lens resolution and sharpness, ensuring compatibility with high-quality lenses.

Suitable for

• Landscape photography requiring long exposures to smooth water and clouds
• Portraits where wider apertures are used in bright light to control depth of field
• Urban and night scenes to create light trails and motion blur
• Analog and digital camera systems needing neutral exposure reduction

Key specifications

• Filter type: neutral density (ND)
• Filter factor: heavy attenuation suitable for long exposures (ND800 equivalent)
• Mount diameter: 58 mm
• Optical material: finely ground and polished special optical glass
• Coating: multi-layer anti-reflective coating on both sides plus hydrophobic/oleophobic outer layer
• Light transmission: uniformly reduced across the visible spectrum for neutral color rendering
• Included: single filter in pack

How to use

Screw the 58 mm ND filter onto the front of a lens with a matching thread size. Compose and focus before applying strong attenuation when possible, as heavy ND filters significantly reduce viewfinder and live-view brightness. For very long exposures, use a stable tripod, enable mirror lock-up or electronic front-curtain shutter if available, and use a remote release or camera timer to avoid vibration. Check white balance and exposure settings; apply exposure compensation or calculate the required shutter speed based on the filter factor.

Usage recommendations

For best results, focus and frame with the filter removed or with a reduced-density method, then attach the B+W 806 and recompose. Use in combination with a sturdy tripod and cable release for exposures longer than a second. Clean the outer coating with a soft microfiber cloth and appropriate lens cleaner to preserve the hydrophobic layer. Avoid overtightening the filter to prevent thread damage.
