Abstract: A camera is provided with an automatic focusing apparatus in which an imaging lens moved for focusing is locked by an identical locking member in both the automatic and manual focusing operation. The focusing apparatus has a single locking member for locking movement of an imaging lens. The locking member is displaced at a predetermined position in accordance with a signal corresponding to a distance to an object in an automatic focusing mode, and is displaced at a position corresponding to a distance set by a manual distance setting member when the focusing mode is switched to the manual mode.

Abstract: The disclosed distance measuring device for a camera capable of measuring the distances of a plurality of objects within a target area comprises center-weighting means for treating the distance information of the object whose image lies near or at the center of the area of the picture frame with a heavier emphasis than those of the other objects, whereby an optimum focusing adjustment is allowed to be formed automatically.
