Abstract
A camera employing an automatic focusing system has a movable objective lens which is automatically moved to a properly focused position in accordance with a distance signal indicative of the distance between the camera and a target object to be photographed from a distance measuring element. The automatic focusing system further includes a discriminator which discriminates whether the distance measuring element properly produces the distance signal or fails to produce such distance signal. When the discriminator detects that the distance measuring element fails to produce the distance signal, the movable objective lens is automatically moved to a pan-focal position.
