Abstract
In a fine-focus actuator, the lens is coupled to a base by extension members. The extension members are rotatably coupled to the base and extend beyond the base. A counter-weight, positioned on the extension members, provides, in the presence of an external inertial force, a torque balancing the torque imposed on the lens holder by the external force. The counter-weight can include elements of the actuator such as magnets, etc.
