The 100 x 150mm Sion Q 1.5-Stop Soft-Edge Graduated Neutral Density Filter from Vu Filters 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 soft-edged line of transition between the density and clear areas. Neutral density filters do not affect the coloration of the image and the density provides a 1.5-stop reduction in light from entering the lens.
Further enhancing image quality is a White Balanced Multi-Coating that ensures that there is little to no color shift. Also, a Flat Wave Coating makes the filter's front surface exceptionally smooth for easier cleaning and maintenance. There is also a UV Rejection Coating that reduces UV reflections and ghosting.
This filter is hand crafted and individually inspected for ensuring quality and uses impact resistant Ultra-White Schott glass for maximum performance. The glass edge is black to prevent internal reflections and helps seals the edge.
