NiSi 3 Stop 0.9 GND Reverse Graduated IR Neutral Density Filter 100X150mm
NiSi Graduated Glass Neutral Density filters adopt our exclusive Nano dual sided gradual Multi-coating, this means ultra violet to near-infrared light can pass through evenly, ensuring a perfectly neutral effect. NiSi filters are precision cut, polished and optically processed to allow for extreme flatness and high parallelism for the highest quality glass, image quality and image crispness. The Optical Nano Multi-Coating provides for a perfectly neutral filter that has no color shift or color cast. This optical Nano coating is also anti-glaring and anti-reflective, alleviating solar glare. This technology was developed for the NiSi IR ND exclusively by NiSi Filters. This is a breakthrough in the world of Digital Imaging.
Compatible with Lee, Hitech, NiSi and Cokin 4×4 Holders.
