摘要：
A lens barrel having a front lens group frame axially movable along its optical axis is stabilized by means of spring elements which urge the frame in a radial direction to a stable position. A rear lens group frame is subsequently radially adjusted so that the optical axis of the rear lens group is in alignment with that of the first lens group.
