Abstract: A camera system, a camera body, and a communication method capable of satisfactorily acquiring lens information necessary for image processing or the like for a frame of a video from an interchangeable lens are provided. Three-wire serial communication is performed in which a request signal is transmitted to the interchangeable lens in synchronization with a synchronization signal (VSYNC) of an imaging element in a video recording mode, and a response signal is received from the interchangeable lens.
