Questions & Answers

FAQ

What is the main purpose of the B+W 86mm Master 810M ND 3.0 10-Stop MRC Nano Neutral Density Filter?

The main purpose of this filter is to reduce the amount of light entering the camera lens, which allows for a wider aperture and slower shutter speed. This is particularly useful in bright conditions where a smaller aperture and faster shutter speed would normally be required to avoid overexposure.

What are the benefits of the multi-layer anti-reflective coating?

The multi-layer anti-reflective coating minimizes reflections and maximizes light transmission, ensuring color fidelity and preventing ghosting and flare. This results in sharper, clearer images.

How does the protective layer on the filter benefit me?

The protective layer offers resistance to dirt and water, making the filter durable and easy to clean. This ensures that the filter remains reliable and effective over time, even in challenging outdoor environments.

Can I use the B+W 86mm Master 810M ND 3.0 10-Stop MRC Nano Neutral Density Filter for direct solar observation?

No, ND filters are not suitable for direct solar observation as they transmit UV and IR rays that can be harmful to the eyes. For safe direct observation of the sun, specialized solar filters are available from astronomy suppliers.

Rated 5 out of 5

Exceptional quality every time

After decades of photography I've only recently begun experimenting with ND filters. When I decided to try this out there wasn't even the briefest hesitation that I would choose B+W. They've been my brand of choice for UV filters for the last twenty years, and I feel absolute confidence in their quality and value.

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.

The advanced thin-film technology employed in this filter not only provides the pure neutral density effect but also incorporates a sophisticated coating combination. This multi-layer anti-reflective coating, with seven layers on each side of the filter, effectively minimizes reflections and maximizes light transmission, ensuring color fidelity and preventing ghosting and flare.

The filter's surface is treated with a top layer that offers resistance to dirt and water, making it durable and easy to clean. This protective layer ensures that the filter remains reliable and effective over time, even in challenging outdoor environments. The uniform light attenuation across the visible spectrum results in color-neutral images that are true to life, making this filter a versatile tool for professional photographers and enthusiasts alike.
