<p>PROBLEM TO BE SOLVED: To provide a camera system and an interchangeable lens by which a shake is accurately corrected in spite of a subject distance by detecting the shake having a different character. SOLUTION: A first vibration detecting unit 7 is provided with angular velocity sensors 7a and 7b detecting the shake by which an optical axis O is inclined. A second vibration detecting unit 8 is provided with acceleration sensors 8a and 8b detecting the shake by which parallel movement to the optical axis O is caused. An installation space is secured on a rear side from a diaphragm part 13 at the inside of a lens barrel 14. Thus, the second vibration detecting unit 8 is installed at a position between the diaphragm part 13 and a lens side mounting part 14a and on the side of a film face 16 as much as possible. Thus, a distance (rotational radius) between the instantaneous center of rotation existing in the vicinity of the film face 16 and the second vibration detecting unit 8 is reduced, so that the influence of angular acceleration is reduced and the shake is accurately corrected.</p> |
