Hoya Variable Density 72 mm

The New HOYA Variable Density II is an upgrade of the original Variable Density filter and features a newly designed rotatable frame with convenient knob allowing for better operation. These filters provide a convenient way adjust exposure control by varying the amount of light entering the camera by 1.5 to 9-stops (equivalent to NDx3-400 or 0... more.45-2.7 density for Cine). The precision double-ring design allows the outer ring to rotate controlling the amount of neutral density anywhere within the 1.5 to 9-stop range. The thin double-ring design also reduces the likelihood of vignetting with wide-angle lenses. These versatile filters allow for many special effects such as being able to control depth of field by using a wider aperture as well as create or control motion blur by being able to choose slow shutter speeds for perfect blurring. Lens Cap Compatibility Hoya Variable Density II filters require a lens cap one size larger than the size of the filter itself. For example the 77mm Hoya Variable Density II Filter requires an 82mm lens cap. Features • Reduces shutter speed for motion blurring effects (water people vehicles etc.) • Allows wider apertures to be used to decrease depth-of-field • Special removeable knob for convenient density adjustment • Convenient density scale • Allows video/cine cameras with limited shutter-speed range to film in bright lighting conditions • For best results with slow shutter speeds always use a tripod! • Available in sizes from 52mm to 82mm diameter
