NiSi Natural Night Filter 58mm

Between mercury vapor, sodium, and low CRI LED streetlights, many undesirable wavelengths of light pollute the night sky. This glow can prevent your camera from capturing the sky properly and degrade night images.

NiSi has developed the Natural Night Filter to block the most common wavelengths of light pollution. Like other NiSi products, this filter is made from high-quality, precision annealed optical glass. Its surface is finely ground and polished to ensure sharpness for today's ultra-high megapixel cameras.

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

The NANO Coating process achieves these benefits without any color shift or loss of sharpness.
