K&F Concept Nano-X magnetic ND1000 filter with adapter ring and cap 49 mm K&F Concept

Podrobný popis

Nano-X Magnetic — neutral density filter 49 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
• Magnetic mount — on and off in a second
• The surface repels water and grease and resists scratches

Longer exposures even in full light

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.

Magnetic lens cap

A magnetic lens cap is included. It holds on the filter by itself and comes off in one move, and when the filter is not fitted it can also be screwed straight onto the lens thread.

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. The filter goes on magnetically — a magnetic adapter ring screws onto the lens and the filter holds itself on. A swap takes a second and nothing has to be screwed. 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.
