K&F Concept Nano-X solar filter ND1000000 67 mm K&F Concept

Podrobný popis

Nano-X — neutral density filter 67 mm, takes light away so you can lengthen the exposure or open the aperture. Such strong attenuation is meant for photographing the sun and eclipses; an ordinary long landscape exposure needs a lower density filter.

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

For photographing the sun

The ND1000000 density cuts 20 stops, the strongest filter in the range. It suits a sun high in the sky, annular eclipses and a solar crescent over the landscape, where a weaker filter would not be enough.

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.

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 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.
