The Genus Eclipse 82mm Fader Variable ND Filter delivers between approximately 2 and 8 stops of light reduction by simply rotating the adjustment ring located on the front of the filter. The smooth rotating action and stepped markings ensure precise adjustment of the amount of light entering your lens. This in turn offers the freedom for you to shoot at a specific shutter speed, aperture and ISO without the risk of overexposure. The variable ND filter allows you to utilise slower shutter speeds in broad daylight to emphasise the movement of elements such as flowing water or clouds. It is also great for DSLR video recording by allowing you to shoot beautifully shallow depth-of-field footage at wide-open apertures without sacrificing your video frame rate. Save time, money and ensure you are ready to maximise your shooting opportunities by replacing your 2x, 4x and 8x Neutral Density (ND) filters with an easy-to-use Genus Eclipse Fader Variable ND Filter.
