46mm Black Mist Diffusion Filter

The B + W Filter Company 46mm Black Mist 1/4 MRC Nano Diffusion Filter threads onto lenses with a 46mm front diameter. It adds a subtle white mist effect that softens highlights and creates gentle halation around bright light sources for a cinematic look.

MRC Nano coating limits reflections

The multi-resistant coating with nano top layer reduces surface reflections to minimise glare and ghosting. It also repels water and oil while providing enhanced scratch resistance for easier cleaning and consistent optical performance.

1/4 strength sets the effect intensity

The quarter-strength diffusion delivers a noticeable but restrained atmospheric quality that enriches blacks without excessive image brightening. Photographers needing stronger or weaker halation must select a different density filter.
