The Lindsey Optics Brilliant² Variable ND provides continuously adjustable light reduction from ND 0.6 to ND 2.4 (2–8 stops) while occupying a single 4x5.65 filter stage. Designed to fit most 4x5.65 matte boxes, it allows exposure adjustments without changing filters and leaves additional stages available for diffusion, polarizers, or effects filters.

The filter features calibrated adjustment markings, standard 0.8 pitch gears, and a 1/4"-20 motor mounting point for remote operation. Its large 138mm optical aperture minimizes vignetting and remains suitable for wide-angle and large-format lens configurations.
