The Hoya 77mm Solas Variable NDX 0.4 to 2.6 Filter is a solid variable neutral density filter that provides an exposure reduction of 1.3 to 8.7 stops. The 0.4 to 2.6 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required. The degree of density is easily controlled by rotating the front filter ring, helping you to predetermine the additional exposure length required. By slowing your exposure time or increasing your aperture, you are able to control depth of field and convey movement more easily.
