The Lee Filters wide-angle adapter ring is suitable for use with wide-angle lenses. It differs from the standard adaptor ring by sitting closer to the front element of the camera's lens. As a result, the likelihood of vignetting is dramatically reduced.
The LEE85 Neutral Density 0.3 (1 stop) Soft Grad has a smooth gradation between the dark and clear areas of the filter. This allows the photographer to selectively adjust exposure across the frame without affecting colour balance.
