B + W Filter Company 39mm Black Mist 1/4 MRC Nano Diffusion Filter #66-1108741

Creative diffusion for 39mm lenses

The B + W Black Mist 1/4 filter fits 39mm filter threads and adds a cinematic glow by softening highlights and lifting shadows. It is intended for photographers and filmmakers who want an atmospheric, vintage-inspired look straight from the camera. The 1/4 density provides a subtle effect that preserves detail while adding halation around bright sources. It is not suited for shooters who need clinical sharpness or clinical contrast in every frame.

Multi-resistant nano coating

The MRC Nano coating reduces reflections, glare and ghosting to maintain contrast and colour fidelity. Its water- and oil-repellent surface resists fingerprints and makes cleaning easier. Enhanced scratch resistance protects the optical glass during regular handling. The matte black filter ring minimises stray reflections. No power draw, thermal output or acoustic noise is generated by this passive optical accessory.

Consistent performance under sustained use

The even coating application ensures uniform diffusion across the frame during long video takes or extended shooting sessions. Optical glass retains clarity without colour shift as the filter warms to ambient temperature. The durable nano layer maintains its hydrophobic and oleophobic properties after repeated cleaning cycles. There is no degradation of the mist effect over time, so the creative look remains predictable from the first shot to the last.
