What this filter does
The B + W 39 mm Black Mist 1/8 diffusion filter adds a subtle white-mist glow around bright highlights while preserving overall image clarity. It is aimed at photographers and videographers who want a cinematic halation effect without heavy softening.
Build and daily handling
The filter ring carries a matte black finish that reduces stray reflections and a nano-coated MRC layer that repels water, oil and fingerprints. Enhanced scratch resistance keeps the Schott glass surface durable during frequent mounting and cleaning.
Limits of the 1/8 strength
The 1/8 density provides only a gentle lift in highlight bloom, so scenes with extreme contrast may still show hard edges. Users needing stronger diffusion or a different thread size will need another filter grade.

Questions about this item
What filter thread size does the 39mm Black Mist 1/8 MRC Nano Diffusion Filter require?
The filter screws directly onto any lens with a 39 mm front thread; no step-up or step-down rings are included.
What physical clearance does the 39mm Black Mist 1/8 MRC Nano Diffusion Filter need when mounted?
Its slim brass ring adds roughly 5 mm of depth, so check that your lens hood or matte box still clears the front element.
How is the 39mm Black Mist 1/8 MRC Nano Diffusion Filter installed, and what step is often missed?
Screw it on until the matte black ring sits flush, then give a gentle quarter-turn to seat the MRC Nano coating evenly; many forget that final seating turn.
