Claim:
1. A compact electromagnetic actuator for driving a lens, the actuator comprising: (a) a lens holder used to hold a lens or a lens assembly which defines an optical axis; (b) an image stabilization (IS) actuator provided at one end of the lens holder for producing a linear motion in a plane perpendicular to the optical axis; (c) an autofocus (AF) actuator provided at an opposite end of the lens holder for producing a linear motion along the optical axis; (d) an AF connection mechanism used to connect the autofocus actuator to the lens holder, wherein the lens holder is engaged and movable with the AF connection mechanism along the optical axis while movable, shiftable, or slidable along a plane perpendicular to the optical axis; and (e) an IS connection mechanism used to connect the image stabilization actuator to the lens holder, wherein the lens holder is engaged and movable with the IS connection mechanism in a plane perpendicular to the optical axis while movable, shiftable, or slidable along the optical axis; (f) wherein the IS connection mechanism is a motion output port in the form of a single plate having a single circular hollow portion at a center thereof, and the single circular hollow portion has a surface being in direct contact with an outer surface of the lens holder, and slidably abutting against and around the outer surface of the lens holder in the plane perpendicular to the optical axis, thereby transferring the motion of the image stabilization actuator to the lens holder, and allowing sliding movement of the lens holder along the optical axis.
