This 82mm HD ND Filter 4-Pack from Neewer includes four filters offering a variety of options for adding neutral density to your images. Increasing neutral density offers finer control over 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. Increased density also makes it possible to shoot using wider lens apertures, helping to isolate a subject from the background.
These filters are made of optical glass for sharpness and feature 30 layers of multicoating for optical light and color transmission. They also have a waterproof and scratch-resistant coating for use in harsh locations and easy cleaning. The thin aluminum filter rings make the filters usable on wide-angle lenses without vignetting.
