ABSTRACT:
In an auto focus camera in which a lens position is changeable in accordance with a photographing mode, based on measured object distance, it is judged whether or not measuring distance can be done, and it is presumed whether or not a person is photographed. In accordance with the result of the judgment and presumption, a focal length of a photographic lens is selected. If distance measuring can not be done or distance measuring data is invalid, focusing operation is executed, based on not the measured distance data but the predetermined distance data which is suitable to a photographing mode of the camera. By this manner, it does not occur that an object image is out of focus badly and a photograph suited for operator's intention can be obtained.
