Abstract

PURPOSE:To make lens system wide in angle and compact by providing the 1st lens group which is fixed to the camera body, and the 2nd lens group which is made movable in the optical axis direction by a focusing device on the image side of a diaphragm. CONSTITUTION:The 1st lens group 2 and a diaphragm 3 are fixed to a camera body 1, and the 2nd lens group 4 which is made movable in the optical axis direction is provided the image side thereof. A focusing device 5 controls the movement of the 2nd lens group 4 according to the detection signals of a circuit 6. Upon ending of photographing in interlocking with winding etc, a means 7 pulls back the 2nd lens group 4 backward against the energizing force, thereby charging the same. Thereby, making the lens system wider in angle and simpler is made possible.
