K&F Concept Nano-X variable ND filter ND4–ND32 72 mm K&F Concept
Kód: AKF01.2529XPodrobný popis
Nano-X variable ND filter ND4–ND32 72 mm, changes the amount of light steplessly as you turn it. It is a favourite for filming on bright days, as it lets you keep a cinematic shutter and a wide aperture without blown highlights or swapping filters between takes.
- 28 anti-reflective layers, reflectance 0.2 %
- Screws onto a lens with a 72 mm thread.
Light under control with one turn
A variable ND replaces a whole set of fixed grey filters — turning the front ring changes how much light gets through, steplessly. While filming the shutter stays at 1/50 s even as the sun goes behind a cloud and comes back, with no need to stop the take or swap a filter.
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. The ring has end stops, so the filter cannot be turned into the position where cheap variable NDs produce the dark cross across the frame. The ND4, ND8, ND16 and ND32 positions are marked on the frame.
