The Lee Filters 75x90mm Seven5 0.6 Hard-Edge Graduated Neutral Density Filter helps to darken specific areas of an image, such as bright skies, while allowing for a normal, unaffected exposure in the other regions of the image. The filter is densest at the edge and tapers to clear by the middle, with a hard-edged line of transition between the density and clear areas.
The Neutral density filter do not affect the coloration of the image and the 0.6 density provides a 2 stop reduction in light from entering the lens. This filter is constructed from a high quality optical resin for both imaging performance and durability. It is compatible with the Seven5 Micro Filter System, which is specifically designed for use with smaller interchangeable lens cameras and this filter measures 3x3.5" / 75x90mm.
