This?ND2-ND400 Blue Multi-Coated Variable ND Filter?from?K&F Concept?is a 82mm variable neutral density filter providing an adjustable light reduction of 1 to 8.6 stops. It darkens the entire image evenly, allowing a photograph to be made with a wider aperture or slower shutter speed than normally required. By slowing the exposure time or increasing the aperture, it is possible to control the depth of field and blur movement easily, creating a dynamic look for streams, waterfalls, landscapes, and more. This multi-coated variable neutral density filter does not affect the coloration of the image. The filter's slim design reduces possible vignetting on wide-angle lenses.
