ABSTRACT:
In the disclosed focus detecting camera, a display is arranged to indicate the drive direction of the camera's photo-taking lens. The camera's focus detecting circuit can detect the in-focus, near-focus, and far-focus positions of the taking lens except when the taking lens is in a drawn out position. The display device shows the drive direction of the lens wherein the display is unable to detect the position.
