The Frazier lens provides an appearance of 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 .
