K&F Concept Nano-X ND filter ND1000 67 mm K&F Concept

Podrobný popis

Nano-X ND filter ND1000 67 mm, takes light away so you can lengthen the exposure or open the aperture. A fixed density suits situations that repeat — long exposures of water and clouds, a blurred background in sunshine or steady light when filming.

• 28 anti-reflective layers, reflectance 0.2 %
• Screws onto a lens with a 67 mm thread.

Longer exposures even in full light

A neutral density filter takes light away without touching the colours. In daylight it lets you shoot wide open with a blurred background, film at 1/50 s by the cine rule, or lengthen the exposure until water melts into mist and people vanish from the frame.

Anti-reflective layers

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. ND1000 cuts ten stops. An exposure of a hundredth of a second becomes around ten seconds even in full sun — the sea smooths into mist, clouds stretch into streaks and passers-by vanish from a busy square.
