The 4 x 5.65″ Full Spectrum Cinema FS ND Filter from NiSi reduces the amount of light entering your lens by 4 stops while prioritizing color accuracy for greater creative control and more visually appealing shots. By producing a consistent effect on light across different colors, it eliminates IR pollution to transmit light evenly throughout the spectrum of UV, visible light, and near-infrared wavelengths. Crafted with durable titanium and anti-reflective coatings, lens flare is minimized while overall contrast is preserved. With shutter and aperture control, this filter allows for shooting at wider apertures or reduced shutter speed while retaining fine granular detail. Hydrophobic and oleophobic coatings on the filter surface provide quick and easy cleanings to keep your filter spotless and functional.
