K&F Concept Nano-X Square Light Pollution Filter 100 × 100 mm K&F Concept

Podrobný popis

A 100 × 100 mm Nano-X square light pollution filter that suppresses the yellow light of street lamps flooding the night sky. Stars and the Milky Way stand out from the orange haze, and night cityscapes get more natural colour and contrast. The bare 2 mm AGC glass slides into standard 100 mm square filter holders.

A night sky without the yellow haze

The filter cuts the wavelengths emitted by common street lamps and so removes the yellow cast from night shots. In astrophotography this raises the contrast of stars and the Milky Way; in night cityscapes colours come closer to reality instead of looking burnt orange.

For 100 mm holders

The 100 × 100 × 2 mm glass has no frame, so it fits 100 mm square filter holders from K&F Concept as well as other brands (Lee, Cokin, NiSi and others).

Glass and coating

The glass carries 28 layers of nano coating with 0.15 % reflectance, which suppresses flare, repels water and grease and resists scratches.
