    • The present invention relates to a camera system. The system includes a selector configured to select one of a still image shooting mode and a movie shooting mode, and a communication unit employing a plurality of communication methods by which communication between an interchangeable lens and a camera body is performed. If the still image shooting mode is selected by the selector and a lens information request command is sent from the camera body to the interchangeable lens, the communication unit operates such that information on the interchangeable lens is sent from the interchangeable lens to the camera body. If the movie shooting mode is selected by the selector, the communication unit operates such that the information on the interchangeable lens is sent from the interchangeable lens to the camera body even without the lens information request command being sent from the camera body to the interchangeable lens.
    • 本发明涉及一种照相机系统。
      该系统包括一个选择器,其被配置为选择静止图像拍摄模式和短片拍摄模式之一,以及
      使用 多个通信方法,通过该方法进行可互换镜头与照相机主体之间的通信。 如果通过选择器选择了静止图像拍摄模式,并且将镜头信息请求命令从相机主体发送到可互换镜头,则通信单元操作,使得可更换镜头上的信息从可更换镜头发送到相机主体。 如果通过选择器选择了短片拍摄模式,则通信单元操作使得即使没有从照相机主体发送到可更换镜头的镜头信息请求命令,可更换镜头上的信息也可从可更换镜头发送到相机主体 。
