The Reversed Telephoto Objective

Lenses of the reversed telephoto type were first used on cameras in the 1920's, although they had been used on projectors for many decades. This type has the advantages of a wide angular field, a long back-focal distance, and the possibility of a high relative aperture; however, the lens tends to be physically large, and existing designs are often complex and expensive. In spite of these disadvantages this type has been extensively used on motion-picture cameras, and recently also for wide-angle lenses on single-lens reflex cameras.
