Kase Wolverine 82mm Variable Neutral Density Filter with Magnetic Lens Cap (2 to 5-Stop)

The Wolverine 82mm Variable Neutral Density Filter from Kase provides an increase in neutral density through a 3-stop range from 2 to 5 stops. Increasing neutral density offers finer control in available shutter speeds or aperture settings for both still and video applications. Using a longer shutter speed makes it possible to increase blur to convey a sense of movement or dial in a video camera frame rate. Increased density also makes it possible to shoot using a wider lens aperture, helping to isolate a subject from the background and increasing bokeh. Density is easily adjusted by using the removable adjustment handle and does not produce the "X" effect common on lower-quality variable ND filters.
