A camera system and interchangeable lens which can accurately compensate for motion causing image blur regardless of the subject range, by detecting motion having different properties. The camera system and interchangeable lens include a first motion detector having angular velocity sensors which detect blurring motion inclined to the optical axis, and a second motion detector having acceleration sensors to detect blurring motion which causes movement perpendicular to the optical axis. The second motion detector is located as close as possible to the film plane, between an aperture unit and a lens side mount unit. As a result, because the distance (radius of rotation) between an instantaneous rotation center, which exists close to the film plane, and the second motion detector becomes small, the effects of angular acceleration become small, and blurring motion can be accurately compensated.
