A 72mm round glass filter with a slim black metal frame

B + W Filter Company

B + W 72mm Master 806M ND 1.8 6-Stop MRC Nano Neutral Density Filter

SKU CH-F6MF-18T43

A 72 mm neutral-density filter that cuts six stops of light for long exposures and wide apertures in bright conditions

  • Reduces light by six stops for longer exposures
  • Enables wider apertures in bright light for shallow depth of field
  • Creates smooth water and motion blur effects with extended shutter speeds
  • Multi-resistant nano coating repels water and dirt for easy cleaning
  • Precision German optical glass maintains image clarity and colour neutrality

72mm ND 1.8 Filter for Photographers

The B+W 72mm Master 806M ND 1.8 6-Stop MRC Nano Neutral Density Filter reduces light entering the lens by six f-stops. It suits both analog and digital cameras. Photographers seeking larger apertures in bright light or long-exposure effects will find it useful. It is not for shooters who need variable density or a different thread size.

Slim Brass Mount Eases Installation

The filter uses a slim brass mounting ring that threads onto 72mm lenses without vignetting on wide angles. Brass resists jamming better than aluminium. The MRC Nano coating repels water and oil, so fingerprints wipe off easily. Over-tightening can still bind the ring; turn only until snug.

Consistent Density During Long Exposures

The filter holds a neutral 1.8 density across the frame during exposures of a second or more. Special glass and thin-film coating prevent colour casts that cheaper filters introduce over time. A tripod keeps the camera steady for the cotton-candy water effect. It does not add infrared leakage that would require extra correction.

Questions about this item

How do I confirm the 6-stop reduction is working after mounting the 72mm Master 806M ND 1.8 filter?

In bright light a shutter speed of 1/60 s should become 1 s at the same aperture, giving the cotton-candy water effect and empty-street look that signal the full 1.8 density is active.

What comes in the box with the 72mm Master 806M ND 1.8 filter and what must I buy separately?

The filter itself is supplied; a 72 mm thread-compatible lens and a sturdy tripod for the long exposures the 6-stop density enables are not included.

Which version of the 72mm Master 806M ND filter should I choose for 6-stop light reduction?

The Master 806M ND 1.8 is the single 6-stop model in this line; the 1.8 density value corresponds to exactly six f-stops of neutral density.
