NiSi NIP-100-ND3.3 100mm ND2000 Filter - 11 Stops, IR Neutral Density

The NiSi 100x100mm ND2000 (3.3) IR Neutral Density Filter is built for photographers who want to push exposure times into multi-second or multi-minute territory in full daylight. At 11 stops of light reduction, it transforms a 1/500s exposure into roughly a 4-second exposure, opening up creative possibilities like silky water, streaking clouds, and ghost-free removal of moving subjects from busy scenes. The IR Neutral Density design is what sets NiSi's offering apart from basic ND filters: by blocking infrared wavelengths alongside visible light, it prevents the warm or magenta color contamination that plagues many high-density filters, delivering results that require minimal post-processing correction.

Constructed from H-K9L optical glass—a material chosen for its low dispersion and high transmission quality—the filter maintains edge-to-edge sharpness that matches the resolving power of modern lenses. NiSi applies Nano dual-side coating to both surfaces, which repels water, oil, and dust, making the filter easier to clean during outdoor shoots. The 100x100mm square format slides into all major holder systems, including Lee, Cokin Z-Pro, Hitech, and NiSi's own 100mm holders, giving photographers flexibility across their existing kit without committing to a proprietary ecosystem.
