摘要： A device for actuating the adjustment mechanism for the combination of lenses on a camera generally known as a zoomMatzkin, Zoom Lens Guide (1962). or ZoomerWebster''s New World Dictionary of the American Language (College Edition) ''''A system of lenses, as in a motion picture or television camera, that can be rapidly adjusted for closeup shots or distance views while keeping the image in focus: a trade-mark.'''' from a remote point proximate to the operator''s position. Conventional cameras either employ a handle mounted on each support of the Zoomar for extending and retracting such lenses or they are equipped with complex internal adjustment mechanisms. In those cameras which rely on handles mounted on the lens support, a fatiguing reach by the operator makes accurate viewing and careful manipulation difficult. To eliminate such difficulty this invention links lens support actuators with controls at the operator''s position.
