NiSi ND16 55mm Swift System 4-Stop VND Filter

The NiSi ND16 55mm Swift System filter provides a precise 4-stop (1.2 density) light reduction for photographers and videographers who need controlled exposure in bright shooting conditions. Built with high definition optical glass and NiSi's proprietary Nano Coating, the filter surface is waterproof, scratch-resistant, and easy to clean in the field. What sets this filter apart from many competitors is its Full Spectrum Neutral Density technology, which actively counteracts the color shifts caused by UV and infrared light that commonly plague lesser ND filters — a critical advantage for video shooters who need consistent white balance across takes.

As part of the NiSi Swift system, this filter uses an innovative friction-mount design that presses securely onto a Swift Base rather than threading on like conventional filters. This makes filter swaps dramatically faster, which is particularly valuable during fast-moving shoots where lighting conditions change quickly. When stacked on top of the NiSi True Color VND, the combined setup provides up to 9 stops of neutral density control, offering a wide range of creative possibilities from subtle exposure adjustments to extreme long-exposure effects in daylight. It is important to note that the filter cannot function independently — a Swift Adapter or True Color VND base is required for any use.
