FAQ

What is the main function of the 40.5mm Master 806M ND 1.8 6-Stop MRC Nano Neutral Density Filter?

The primary function of this ND filter is to reduce the amount of light entering the camera lens by six f-stops. This allows for longer exposure times without altering the aperture or depth of field, creating unique photographic effects such as rendering moving water as a soft, hazy blur.

What materials are used in the construction of this ND filter?

The filter is crafted from finely ground and polished special glass. This material ensures exceptional optical quality that doesn't compromise the performance of your high-end lens.

What is the benefit of the filter's coating combination?

The unique coating combination includes a multi-layer anti-reflective component that eliminates unwanted reflections. An additional outer layer has dirt- and water-repellent properties, providing robust protection for the filter and simplifying maintenance.

Can I use this ND filter for direct visual solar observation?

No, ND filters are not suitable for direct visual solar observation due to the risk of blinding, as they allow UV- and IR-rays that can harm the eyes. For safe solar observation, please consider special sun filters available from astronomy suppliers.

Does what it says on the tin.

I'm a big fan of B+W filters so I knew when I started to get into M glass that I was gonna need a few. For one thing I wanted an ND filter to be able to achieve some creamy bokeh shots and it does exactly that. Very well made, filters 100% recommend.
