The Hoya Variable Density II 72 mm ND filter is a variable ND filter designed to control exposure in photo and video without changing the other camera or camcorder settings. It replaces a series of fixed-density ND filters with continuous adjustment from ND 0.45, equivalent to 3x, to ND 2.6, equivalent to 400x, a range of 1.5 to 9 stops. The Hoya variable ND 72 mm filter allows for a wider aperture in bright light or longer exposure times, for example to achieve a motion blur effect. ND filters evenly darken the entire image surface, allowing for wider apertures or longer exposure times.

Compared to the previous version, the Variable Density II line features additional anti-reflective coatings on the glass surface, reducing unwanted reflections and glare. The thinner mount is designed to reduce the risk of vignetting, while the outer diameter is slightly larger. A small knob makes it easy to set the desired darkening level.

The filter is designed for photographers and videomakers working in variable lighting conditions: density can be adjusted directly during shooting, without having to swap the filter mounted on the lens.
