The NiSi 77mm Natural Night Filter is a new addition to the NiSi range and our first filter exclusive for night photography. Between mercury vapour, sodium, Low CRI streetlights, there are many undesirable wavelengths of light that pollute the night sky. The glow from these can keep your camera from seeing the sky correctly and affect your night images. Because of this, 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.
