Black Mist scatters the light around bright areas — street lamps take on a gentle glow, blown highlights soften and skin loses its digital hardness. Contrast in the deep shadows drops a little, so the picture looks more filmic straight out of the camera. Unlike an effect added in post, the diffusion follows the actual light in the scene.

The glass carries 28 anti-reflective layers and reflects only 0.2 % of the light, so no ghosting or veiling appears against the light.

The surface repels water and grease, so drops run off and fingerprints wipe away without smears; the coating also stands up to cleaning in the field.

The 1/8 strength is the gentler of the usual pair: highlights get a hint of bloom and skin softens, while the image keeps its detail and contrast. For everyday shooting this is the strength that can stay on the lens.
