The Brilliant2 4 x 5.65"/138mm Variable Neutral Density Filter from Lindsey Optics uses two 138mm circular polarizers to create a single variable ND in a 4 x 5.65" frame. This aluminum and glass filter occupies two filter slots in a 4 x 5.65" matte box and rotates using two geared thumbwheels. It offers 2 to 8 stops of neutral-color light reduction and features IR pollution reduction and an anti-reflective multi-coating.

With a 5.1" clear aperture, the Brilliant2 Variable ND is suitable for use with both wide-angle primes and large zoom lenses.
