Hoya Variable Density II 67 mm is a variable ND filter with a 67 mm thread, designed for photographers and videographers who need to adjust exposure continuously without changing filters on the lens. The Hoya variable ND filter covers a range from ND3 to ND400, equivalent to 1.5 to 9 stops, replacing a series of fixed-density ND filters. It adapts to light variations during shooting, allowing for wider apertures in bright light or longer shutter speeds to render motion. Compared to the previous version in the line, the glass surface features multi-coated anti-reflection treatments to limit reflections and flare. The frame is thinner to reduce vignetting risk, with an outer diameter slightly larger than the threaded part, and a small knob simplifies setting the desired darkening level. The 67 mm variable ND filter mounts on lenses with a 67 mm filter diameter, for both photography and video shooting. A protective case is included in the package. Continuous density control allows for exposure adjustment without changing other camera parameters, and in video shooting, it maintains aperture and shutter at chosen values when light changes. Those seeking a Hoya variable ND 67 mm solution instead of multiple fixed-density filters will find rapid adjustment and a wide range of available densities in this model.
