Abstract
To shift the movable lenses of a verifocal objective, or to adjust the leaves of an iris diaphragm, a flat or cylindrically curved control element is formed with camming grooves coacting with projections on the controlled members. The control element is a deformable foil, e.g. of sheet metal, in which the camming grooves are formed by deep-drawing. The foil rests against a backing element with which it is positively connected by a tongue-and-groove coupling or the like and which entrains the control element upon being rotated about their common axis by an external force.
