CAMERA BODY, INTERCHANGEABLE LENS UNIT, AND CAMERA SYSTEM

摘要

A camera body (3) has a cross-shaped operation key (27) and a body microcomputer (10). The body microcomputer (10) can obtain lens information on an interchangeable lens unit (2) from the lens unit (2). The body microcomputer (10) determines, based on the lens information, whether the interchangeable lens unit (2) is compatible with an electric zoom operation. Further, based on the result of the determination, the body microcomputer (10) enables zoom operation by the cross-shaped operation key (27).
