A camera having an automatic focusing device, capable of automatically driving a lens to a shooting lens position where it can simultaneously focus different objects on different positions. The camera has a focus detection circuit capable of detecting focusing positions where the lens is focused on the respective objects. When one of the focusing positions is beyond the limit of drive of the lens, the driving to the shooting lens position is judged to be impossible and the control for driving the lens to the shooting lens position is prohibited.

A camera having an automatic focusing device comprising: (a) a focus detection circuit for detecting a state of focusing of an image forming optical system; (b) a driving circuit for driving said image forming optical system between a first in-focus position where said image forming optical system is focused on a first object and a second in-focusing position where said image forming optical system is focused on a second object, said first and second in-focus positions being detected by said focus detection circuit; (c) discrimination means for discriminating whether one or said first and second in-focus positions is beyond a driving limit of said image forming optical system; and (d) prohibiting means for prohibiting the driving of said image forming optical system to an intermediate position between said first and second in-focus positions when said discrimination means has discriminated that one of said first and second in-focus positions is beyond a driving limit of said image forming optical system.
