ABSTRACT:
This specification discloses a camera which comprises a lens driven by an electric motor and a distance detecting circuit and in which change-over is automatically effected between an automatic focus adjusting mode in which the lens is usually driven by a signal from the distance detecting circuit and a manual focus adjusting mode in which the lens is driven manually when a signal for driving the lens is not put out from the distance detecting circuit, that is, in the case of the concurrence of far focus and near focus of an object to be photographed or in a case where the object to be photographed is of a low contrast, and in which even during the manual focus adjusting mode, the distance detecting circuit is operated and when an in-focus signal is put out from the distance detecting circuit, the lens is stopped for a predetermined time.
