<p>In an automatic focus camera having a biased focusing ring (1, Fig. 1), the focusing and the diaphragm aperture may be set at fixed values without use of the automatic focusing for use with flash. As shown, on pop- up of a flash unit 16a, lever 22 is related anticlockwise to rotate change-over ring 11 clockwise and allow pin 12a of biased limiting lever 12 to make contact with portions 1c and d of focusing ring 1 so as to stop ring 1 and set the aperture in dependence on the flash guide number. <IMAGE></p> |
