Paper Abstract

TELEPHOTO LENS - a positive front component widely separated from a negative rear component. The second principal plane lies outside the end of the system. Its advantage is compactness in the lens barrel length for a given focal length (f). A normal lens gives better definition and covers a wider field at a higher relative aperture than a telephoto lens.
