ABSTRACT:
A camera which permits automatic focusing and manual focusing comprising an objective lens structure, an automatically focusing device, and actuating means. The objective lens structure includes a focusing lens system, a focusing lens system supporting member, biasing means for biasing the supporting member in one direction of the optic axis of the lens system, and an extraneously operable, manually focusing operating member for moving the supporting member in said one direction through the biasing means and for directly moving the supporting member in the opposite direction. The actuating means is used for moving the supporting member in the direction of the optic axis against the biasing force of the biasing means by the output of the automatically focusing device, independently of the manually focusing operating member.
