NiSi (3.3) 11 Stop 100x100mm (3.94x3.94") Neutral Density Glass Filter

The Nisi 100x100mm Neutral Density Filters are specially designed for landscape photographers. This filter measures 100 x 100mm and is compatible with the Nisi 100mm filter holders as well as any standard holder for 2mm thick filters. 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 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 a color shift or loss in sharpness.
