Hoya 82MM VARIABLE DENSITY II

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 0.45-2.7 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 CompatibilityHoya 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
