Abstract:
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.
