ABSTRACT:
A camera includes a photographic optical system including a focusing lens group located at the front of the photographic optical system and a lens frame for supporting the focusing lens group, which projects forwardly from an infinite focus position to a shortest focus position for a focusing operation. A lens opening is provided on the camera, which exposes the focusing lens group to outside the camera. The lens opening is formed so as to allow the lens frame to project forwardly through the lens opening when the lens frame moves to the shortest focus position.
