Abstract
PURPOSE: To prevent the movement of the lens owing to the own weight of the lens and prevent focus deviation even for the photographing of both horizontal and vertical directions by changing the load upon the lens movement according to the horizontal and vertical posture photographing of the camera.
CONSTITUTION: In the photographing close to a horizontal posture, an operating ring 1 is put in the first click position and a click spring 3 is fitted in the first click groove 2a. In this state, a spring piece 12a is riding on the protruding part 4b' of an outer barrel 4b, so spring action does not act. Hence, the turning of the ring 1 may be done smoothly. Next, in the photographing close to a vertical posture, the operating ring 1 is fitted into the second click groove 2b, which the spring piece 12a is held between the protruding part 4b' of the helicoid barrel and a stationary barrel 18. Hence, the spring acts to make the turning of the operating ring heavy, whereby the movement of the lens owing to its own weight is prevented.
