Abstract
Provided are a camera system, a camera, an interchangeable lens, and a compatibility determination method of a camera system capable of simply and quickly determining compatibility between the camera and the interchangeable lens. An eleventh contact (CC) provided in a camera () and an eleventh contact (LC) provided in an interchangeable lens () are composed of contacts in which an open drain output is possible. In a case where the camera () supports a specific function, the eleventh contact (CC) on a camera-side is set to a first polarity. In a case where the camera () does not support the specific function, the eleventh contact (CC) on the camera side is set to a second polarity. In a case where the interchangeable lens () supports the specific function, the eleventh contact (LC) on an interchangeable lens-side is set to the first polarity. In a case where the interchangeable lens () does not support the specific function, the eleventh contact (LC) on the interchangeable lens side is set to the second polarity. The eleventh contact (CC) on the camera side and the eleventh contact (LC) on the interchangeable lens side, which are mutually connected, are at the first polarity only in a case where both contacts are at the first polarity. Therefore, in a case where the polarities of the eleventh contact (CC) on the camera side and the eleventh contact (LC) on the interchangeable lens side are detected, it is possible to determine presence or absence of compatibility in both the camera () and the interchangeable lens ().
