Abstract
Disclosed is an adjusting device for a lens system having at least two optical elements displaceable parallel to the optical axis, the paths of displacement of which are subject to different courses of movement. To produce linear displacement parallel to the optical axis, a tube is arranged in the adjusting ring, which is rotatable and displaceable parallel to the optical axis. This tube serves as the mount for an optical element and has in the wall of one of its ends a guide groove. A hollow cylinder, serving as the mount for the other optical element and being displaceably mounted in the tube, has a guide element mounted on its external wall which engages the guide groove. Means are provided to drivingly connect the adjusting ring and the hollow cylinder.
