Abstract:
To provide an interchangeable lens, a camera body, a camera system, and a method for controlling the same, with which a highly efficient and stable image blur correction effect can be obtained. A camera system (1) has a camera body (10) and an interchangeable lens (20) which is attachable to and detachable from the camera body (10). The camera body (10) has an imaging unit (120) for imaging a subject through the interchangeable lens (20), and a sequence microcomputer (100) capable of sending and receiving information to and from a lens microcomputer (200) and for controlling the imaging operation of an imaging unit (120). The interchangeable lens (20) includes a shake detection unit (201) for detecting shake in the camera system (1), an image blur correction device (210) for adjusting the optical path from a subject to the camera body (10) and thereby correcting the blurring of an image caused by shaking of the camera system (1), and the lens microcomputer (200) capable of sending and receiving information to and from the sequence microcomputer (100), and for controlling the drive of the image blur correction device (210) according to the amount of shake detected by the shake detection unit (201). The imaging optical system of the interchangeable lens (20) includes an aperture unit (206) which can adjust the imaging condition. The lens microcomputer (200) actuates the shake correction device (210) once a first set time has elapsed since the receipt of an adjustment command from the sequence microcomputer (100).
