Abstract:
1. A camera system, comprising: an interchangeable lens unit having an imaging optical system configured to forming an optical image of a subject, a focus adjuster configured to optically adjust the focus state of the optical image, and a lens controller configured to control the operation of the focus adjuster; and a camera body having an imaging unit configured to convert an optical image of the subject into an image signal and configured to acquire an image of the subject, a focus detector configured to detect the focus state of the optical image by contrast detection method on the basis of the image signal, a control interface with which control information can be inputted from the outside, and a body controller controlling the operation of the imaging unit and with which information can be exchanged with the lens controller, wherein the lens controller has lens information related to the interchangeable lens unit, the lens information includes information related to whether or not the interchangeable lens unit is compatible with a moving picture mode, the body controller has a decision part configured to decide whether or not the interchangeable lens unit is compatible with the moving picture mode on the basis of the lens information, and a mode switching controller with which the operation of the imaging unit can be set to either still picture mode or moving picture mode on the basis of the decision result of the decision part or the control information, and if the decision part decides that the interchangeable lens unit is not compatible with the moving picture mode, the mode switching controller prevents the operation of the imaging unit from being set to the moving picture mode regardless of the control information.
