HDTV camera lenses and prism systems must be capable of twice the resolution of conventional lenses and optics used for today's TV standards, and produce 35mm film color quality on a large screen with a minimum aspect ratio of 5:3. - The large picture size and aspect ratio require a much higher degree of sharpness to attain the color fidelity. Resolution, brightness and contrast all contribute to the sharpness of the picture. - The discussion presents the most important design considerations for a zoom lens and prism system that produce consistently high quality pictures regardless of F stop and focal length.
