ABSTRACT:
An optical lens barrel having a lens group which serves as a vibration compensation lens group and a focusing lens group. The lens group is held by a holder movably secured to a plate. The lens group is movable within the plate on a plane perpendicular to an optical axis of the lens group via a pair of DC motors and associated gear trains. The DC motors and associated gear trains are mounted on the plate. The plate is slidably movable parallel to the optical axis of the lens group by a stepping motor via a series of concentric drive rings disposed around the plate. The drive rings also actuate an aperture mechanism which serves as a shutter. This reduces both the number of lenses and components needed to provide vibration compensation and autofocusing functions.
