NiSi Natural Night Filter - 100x100mm

The NiSi 100x100mm Natural Night Filter is a new addition to the NiSi range and our first filter exclusive for night photography.  Between mercury vapor, 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 properly and effect 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.

The NiSi Natural Night Filter features NiSi’s unique NANO Coating technology. This multi-layer coating reduces reflection on the surface of the filter to help with 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 your glass. The NANO Coating process achieves this without loss in sharpness.

The NiSi 100mm filter system is great for cameras with lenses that have a standard filter thread from 49 mm to 95mm. 

This 100mmx100mm filter is compatible with the NiSi 100mm filter system.
