Abstract
In an automatic focusing camera in which a focus detector determines the amount of movement of a phototaking lens on the basis of light from an object via a moving mirror in the phototaking optical path, timing of the start of the actuation of a mirror operating means, which retracts the mirror from the phototaking optical path, is controlled so that retraction of the moving mirror is completed substantially at the same time that focusing movement of the lens is completed. The time from the start of focal point detection to the completion of lens movement and mirror retraction can be made constant, and the shot speed in continuous photography can be selected.
