K&F Concept Nano-X 2-in-1 filter: Black Mist 1/4 and variable ND2–ND400 77 mm K&F Concept

Podrobný popis

Nano-X — Black Mist filter 77 mm, softens the highlights and takes off digital sharpness. It suits portraits, night streets and video wherever the picture should look softer and less digital without being reworked on the computer afterwards.

• 28 anti-reflective layers, reflectance 0.2 %
• Screws onto a lens with a 77 mm thread.

Softer highlights, a film look

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.

One glass does two jobs at once: it diffuses highlights like a Black Mist 1/4 and at the same time cuts one to nine stops of light, continuously. A backlit portrait or video in the midday sun can be shot with the aperture open without stacking two filters on the lens; the strength is set with a lever on the frame.
