とするカメラシステム。[Claims for Utility Model Registration] Consisting of a camera body and a lens replaceably attached to the camera body, within the lens there is a lens driving means for driving a focus lens, and a lens for controlling the operation of the lens. a detection means for detecting a focus state or a distance to a subject within the camera body; and a calculation means for calculating data regarding automatic focusing based on the detection result of the detection means; body-side control means for controlling the operation of the camera body, further comprising communication means for transmitting and receiving data between the lens and the camera body, and transmitting data regarding the automatic focusing to the communication means. Therefore, in a camera system that automatically adjusts the focus by transmitting data to the lens, the type of data related to the automatic focusing is indicated in the data transmitted from the camera body to the lens by the communication means. A camera system characterized by including information.
