Abstract

Relaxation of various restrictions has led to new zoom lens types which include multiple zooming groups and advanced concepts for focusing. New designs can now rival fixed focal length lenses for most applications, and with the use of aspherics can be low cost. Gaussian optics and primary aberrations are used to obtain good starting design types.
