Abstract: A coarse and fine adjustment device especially for focusing a lens system in which both the coarse and fine adjustment are transmitted by two levers pivotally connected together. The coarse or fine adjustment levers are moved by control means which may comprise screw-threaded pins, cam surfaces or an inclined plane acting upon the levers. Only one of the levers is in actual contact with the element to be moved.
