46mm 10-Stop Neutral Density Filter
The B+W Master 810M ND 3.0 is a 46mm neutral density filter that reduces light entering the camera by ten f-stops. It is designed for photographers who want precise exposure control with both analog and digital cameras. The filter uses special optical glass with a 7-layer multi-resistant coating on each side to minimise reflections and preserve lens performance. A nano coating adds further surface protection.
Long-exposure and wide-aperture shooters
This filter suits photographers creating silky water effects, motion blur or deserted urban scenes through extended shutter speeds. It also allows wider apertures for selective focus in bright conditions without overexposure. Photographers who need variable density, graduated transitions or filter diameters other than 46mm should look at alternative filter types.
Threads onto 46mm lens fronts
The filter mounts directly to any lens with a 46mm filter thread, leaving the lens hood or cap compatibility unchanged. Its slim frame reduces the risk of vignetting on wide-angle lenses. By cutting ten stops of light uniformly across the spectrum, it frees the photographer to choose any shutter speed or aperture combination the scene demands without shifting colour balance.

Questions about this item
What thread size must my lens have to accept this 46 mm filter?
Your lens needs a 46 mm front filter thread; check the barrel or cap for the Ø46 marking.
Will the 10-stop density work with my older manual-focus lenses?
Yes, the filter is suitable for both analog and digital cameras, so it works with legacy manual lenses.
How can I verify the filter is giving a true 10-stop reduction after mounting it?
Meter a scene without the filter, then meter again with it fitted; the exposure should shift by ten full stops.
