Development of a process camera lens with variable focal length
Abstract
Process cameras of today are equipped exclusively with fixed focal length lenses. The development of a process lens with variable focal length is described. The design principles of its optical, mechanical, and electronic groups of components are explained. The prototype of the new lens reaches the image quality of fixed focal length lenses.
