The Singh-Ray 100 x 150mm George Lepp 0.9 Neutral Density Filter is a solid ND filter that provides a 3-stop reduction in exposure. This 0.9 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 rectangular filters are constructed from CR-39 optical resin for high image clarity and overall durability. This filter is compatible with the Cokin Z-Pro filter holder and measures 3.9 x 5.9" / 100 x 150mm.
