The Nisi 180x180mm Neutral Density Filters are specially designed for landscape photographers. This filter measures 180 x 180mm and is compatible with the Nisi 180mm filter holders. Nisi Neutral Density filters feature a foam gasket on the rear of the filter to prevent light leaks during long exposures.
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 Neutral Density Filters feature 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 a color shift or loss in sharpness.
