Nisi 52mm 4-Stop Variable Neutral Density Filter for True Color VND & Swift System

The NiSi ND16 4 Stop Filter is designed for the NiSi True Color VND Swift System and extends the range of the NiSi True Color 1 to 5 stop Variable ND Filter to a broader 5 to 9 stop range, ideal for bright shooting conditions that require stronger light reduction. The Swift System allows filters to be easily added by pressing them onto the front of the base NiSi True Color 1 to 5 stop VND, enabling seamless expansion without the need for complicated mounting. With the addition of the ND16 filter, photographers gain greater flexibility in controlling exposure, especially in harsh lighting. This filter features a new multi-ti coating that provides anti-reflective and waterproof properties, while delivering four full stops of neutral light reduction and maintaining accurate color transmission. It also offers precise stop control, preserving image fidelity across a wide tonal range. When stacking filters, be aware that vignetting can occur at wider focal lengths. Refer to recommended focal lengths to help prevent this issue.
