The Development of the Zoom Lens

Rudolf Kingslake

Zoom, or varifocal, lenses have been known since 1930, but they were seldom used until after the second world war, when they became generally applied to television cameras. The past ten years have seen the development of several types of zoom lens for 8mm and 16mm motion-picture cameras. These are either mechanically or optically compensated, and necessarily contain many lens elements. The optical design is difficult, and it is only recently that zoom lenses comparable to ordinary cine lenses have become available.
