Abstract

PURPOSE:To faciliate the assembly control work and the working of parts, by constituting a focal control ring with plural independent parts. CONSTITUTION:When a manual control ring 3 of a ring block is turned, lens groups L1 and L2 move in direction A for instance by the function of a helicoid screw 2a. Thus the focus is controlled, and at the same time the lense group L1 moves in direction B to the group L2 via a lead pin 6a and a pin 12 to perform a correction of aberration. During the control of assembly, the ring 3 is removed. The an intermediate ring 2 is screwed up to a reference position while fitting a mount part 1 and the 2nd lens group holding barrel 8. Then a screw 7 is loosened to turn slightly a lead ring 6 and thus to control a distance (l). Thereafter, the ring 6 is fixed again to the ring 2 and then the ring 3 is fitted to the ring 2. Then the distance scale is set at a fixed index, and the ring 3 is fixed to the ring 2. In such way, the assembly control work and the working of parts can be facilitated.
