Overview

The NiSi 77mm Swift System VND Kit is a professional-grade light control solution designed for photographers and videographers who demand color accuracy alongside flexible exposure adjustment. The kit centers on a true color variable neutral density filter that smoothly adjusts from 1 to 5 stops of light reduction, allowing you to open up your aperture for shallow depth of field or extend shutter speeds for motion blur effects even in bright conditions. The included ND16 filter provides a fixed 4-stop reduction and can be stacked directly onto the variable ND via the Swift pressure mount, extending the total range to 6 through 9 stops for situations requiring heavy light reduction such as long exposures in daylight.

What distinguishes the NiSi Swift system from traditional screw-in filters is its friction-based pressure mount, which eliminates the risk of cross-threading and dramatically speeds up filter changes in the field. The HD optical glass is nano-coated on both sides to resist smudges, water droplets, and dust, while the true color film layer works to prevent the green and magenta color casts that plague many variable ND filters across their adjustment range. At 77mm, the filter fits a wide range of professional lenses directly and can be adapted to smaller thread sizes with step-up rings. The system is designed to avoid vignetting when stacked at 18mm and above, making it suitable for a broad range of focal lengths commonly used in video and landscape photography.
