The Singh-Ray 82mm George Lepp 0.3 Neutral Density Filter is a solid ND filter that provides a 1-stop reduction in exposure. This 0.3 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required. By slowing your exposure time or increasing your aperture, you are able to control depth of field and convey movement more easily.
Singh-Ray ring-mounted filters are constructed from highly polished glass and specially formulated optical laminates. The standard ring mount design measures 5.5mm-thick and features front filter threads for stacking of additional filters.
