NiSi 100x150mm Nano Medium-Edge Graduated IRND 0.9 (3 Stop) Filter

The Nisi 100x150mm Medium Graduated Neutral Density Filter is specially designed for landscape photographers. This filter measures 100 x 150mm and is compatible with the Nisi 100mm filter holders as well as any other standard 2mm thick holder. The filter can be repositioned in the holder allowing you to get the best result. The Nisi Medium Graduated Neutral Density Filter is designed with a smooth, but noticeable, gradation from clear to dark, allowing you to work with uneven horizons easily. 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 Medium Graduated Neutral Density 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 a color shift or loss in sharpness.
