Abstract
L'invention concerne un dispositif de commande d'objectif à distance focale variable pour une caméra de télévision. Il comporte plusieurs unités destinées à actionner la bague de commande de diaphragme, la bague de commande de distance focale et la bague de commande de foyer. Ces unités sont reliées entre elles et avec le corps de la caméra par des dispositifs électriques et mécaniques permettant aussi bien la commande automatique que la commande manuelle. Une commande à distance de ces unités est également prévue L'invention s'applique notamment à des caméras de télévision portatives.
