gives you
The GPL Vari-Focal Lens is equally useful, studio and field; fits all monochrome and color image orthicon cameras.
The GPL Vari-Focal Lens can handle an entire show with one camera ; can perform most work ordinarily requiring two chains.
The GPL Vari-Focal Lens has a focal range nearly twice that of any other lens in the industry; can make a 10:1 change in focal length in two 5:1 steps — from 3" to 15" and 6" to 30". Once focused, object remains sharply focused, including corners, as focal length is varied.
The GPL Vari-Focal Lens has the same standard of resolution as high quality camera lenses of fixed focal length.
The GPL Vari-Focal Lens can zoom from a long shot to an extreme close-up, continuously, without
advantages
disturbing pick-up continuity or camera orientation. Speed of full zoom is variable from 2 to 30 seconds.
The GPL Vari-Focal Lens eliminates the need and expense of additional lenses.
The GPL Vari-Focal Lens is silently motor-driven ; can be operated from camera or control room.
g The GPL Vari-Focal Lens is fully color-corrected ; has flat field over entire range.
