NiSi Natural Night Filter 55mm

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 properly capturing the sky and ruin your night images.

NiSi has created the Natural Night Filter to block the most common wavelengths of light pollution. Like the rest of the NiSi line, this filter is made of 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 to help prevent ghosting and flare. It also includes a protective layer that makes it easy to wipe off water, dust, and oil from the filter without worrying about scratching the glass.

The NANO Coating process achieves this without any color shift or loss in sharpness.
