The NUANCES Variable Neutral Density 2-400 provides an equivalent ND factor of 1-8 stops. Using high quality Schott B270 Glass for the base, Cokin uses a patented ND coating application process to ensure uniform density and no vignetting.  A nano-metallic alloy is then applied on both sides of the filter to reduce color shift and increase sharpness and contrast.

A variable ND filter is a great tool for photographers and cinematographers. It allows you to reach longer exposure shutter speeds or achieve a shallow depth-of-field in bright light conditions. Cinematographers will love the filters ability to attain the perfect shutter speed to frame-rate combination in all lighting conditions.
