Frazier Lens

The Frazier lens is a special camera lens designed by Australian photographer Jim Frazier. The Frazier lens provides a massive depth of field, allowing the foreground and background of an image to be in focus. Frazier's lenses have been widely used in Hollywood and wildlife cinematography. In addition to its unique depth of field properties, the Frazier lens is significantly smaller than previous deep focus lenses allowing more versatility and flexibility to cinematographers. The main feature of the lens, an extended tube with a rotating prism, allows cinematographers to place the camera in a variety of positions for a given shot. Cinematographers then rotate the prism to correct the horizon. This feature allows directors and cameramen to achieve shots in minutes that previously took cinematographers hours in rigging and designing special sets to accommodate shooting positions.
