Abstract:
1. A lens barrel comprising: a rear barrel to which an imaging device is attachable; an imaging optical system leading a subject image to the imaging device; and an image blur correcting unit moving a shift lens forming the imaging optical system in a plane perpendicular to an optical axis of the imaging optical system, wherein the image blur correcting unit includes a base supporting the shift lens in a plane perpendicular to the optical axis of the imaging optical system, along a first virtual axis extending and a second virtual axis that extends in a direction perpendicular to the first virtual axis in a plane perpendicular to an optical axis of the imaging optical system, and the lens barrel includes a support mechanism supporting the base to be movable relative to the rear barrel along a plane perpendicular to the optical axis; and a fixing device fixing the base to the rear barrel.
