Abstract:
1. A camera system for imaging a subject, comprising: a camera body having an imaging unit for imaging the subject, and a body control unit for controlling the operation of the imaging unit; and an interchangeable lens being attachable to and detachable from the camera body, and including a shake detection unit for detecting shake in the camera system, an image blur correction unit for adjusting the optical path from the subject to the camera body and thereby correcting the blurring of an image caused by shaking of the camera system, a lens control unit for controlling the drive of the image blur correction unit according to the amount of shake detected by the shake detection unit, and an imaging optical system for conducting the optical image of the subject to the imaging unit, wherein the body control unit can send and receive information to and from the lens control unit, the imaging optical system includes a condition adjustment unit which can adjust an imaging condition, the lens control unit starts an adjustment operation in the condition adjustment unit based on an adjustment command sent from the body control unit for adjusting the imaging condition, and actuates the image blur correction unit once a first set time has elapsed since the receipt of the adjustment command, the body control unit sends a required exposure preparation time from a start of an exposure preparation until the completion thereof in the camera body to the lens control unit, prior to sending the adjustment command, and the lens control unit determines the first set time based on the required exposure preparation time and a required correction stabilization time from the actuation of the image blur correction unit until a predetermined image blur correction effect is obtained.
