Paper Abstract

This paper summarizes two subjects; one is theoretical development of zoom lenses and another is their configurational advances.In the former part, a general zoom equation is presented and its paraxial analysis is, in general, derived. In the latter part, it is enumerated and analyzed newly developed configurations of zoom lenses, such as a built-in range extender, an electronically compensated zoomlens, a two-component telephoto type and others.
