2. Related Art
JP4-280239A discloses an interchangeable lens type camera apparatus. A lens unit that is mounted to a camera body of this camera apparatus has a drive system that regulates automatic focus and controls automatic exposure. The lens unit has status information about the lens unit. This camera apparatus controls the lens unit from the camera body by communicating various control information and the status information between the camera body and the lens unit.
The camera apparatus disclosed in JP4-280239A, when recording moving images, may not accurately know a drive condition of a focus lens in some cases. For this reason, when autofocus is controlled, false control is occasionally made.
