NiSi Filter Natural Night 67mm

NiSi Filter Natural Night 67mm – Blocks light pollution wavelengths for cleaner night colors

Use the NiSi Natural Night Filter for night scenes and astrophotography. It reduces the glow from common streetlight sources so your camera can capture the sky more accurately. NiSi designed this filter to block the most common wavelengths of light pollution that interfere with night images.

What light pollution the filter targets

Streetlights such as mercury vapor, sodium, and low CRI LED produce undesirable wavelengths that pollute the night sky. These wavelengths create a glow that can prevent your camera from seeing stars and subtle sky tones properly. The NiSi Natural Night Filter blocks those common wavelengths, giving you cleaner and more natural colors in nighttime photos.

Optical quality and surface finish

NiSi builds this filter from high-quality, precision annealed optical glass. The surface receives fine grinding and polishing to ensure it preserves sharpness for today's ultra high megapixel cameras. As a result, you maintain image detail while reducing unwanted light pollution effects.

NANO Coating: reflection control and protection

The NiSi Natural Night Filter features NiSi's unique NANO Coating technology. This multi-layer coating reduces surface reflections to help limit ghosting and flare. Additionally, the coating includes a protective layer that makes it easy to wipe water, dust and oil off the filter without worrying about scratching the glass.

Importantly, the NANO Coating process achieves these benefits without introducing color shift or any loss in sharpness.
