B + W 43mm Master 806M ND 1.8 6-Stop MRC Nano Neutral Density Filter

43mm Master 806M ND 1.8 6-Stop Filter

This 43mm neutral density filter reduces light by six f-stops, extending exposure times for creative long-exposure photography. It suits photographers who want to capture motion blur in bright conditions or maintain wide apertures for shallow depth of field. The Master 806M series is built for high optical standards without degrading lens performance. It is not for shooters who need variable density or stronger light reduction than 1.8 optical density.

Multi-resistant and nano coating performance

The seven-layer multi-resistant coating on each side cuts reflections and maximizes light transmission for clear, ghosting-free images. A durable nano coating layer repels dirt, moisture and scratches, making the filter easier to clean in the field. Finely ground and polished special glass ensures uniform attenuation across the visible spectrum for color-neutral results. The thin-film construction maintains consistent density during extended use under strong illumination.

Upgrading from basic ND filters

This filter replaces uncoated or single-coated ND filters that suffer from flare, color casts and difficult cleaning. The jump is worth it when you require reliable six-stop reduction with minimal reflection loss and robust surface protection. It also supersedes lower-density filters when exposure times of one second or longer are needed at base ISO. Buyers who only need two or three stops of reduction will find this density excessive.
