The LEE Filters 75 x 90mm Seven5 Big Stopper 3.0 Neutral Density Filter is a solid neutral density filter providing a 10-stop reduction in exposure. This 3.0 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.
This filter is constructed from a high quality optical glass for high definition and clarity. It is compatible with the Seven5 Filter System, which is specifically designed for use with smaller interchangeable lens cameras. This filter measures 3 x 3.5" / 75 x 90mm.
