ABSTRACT:
A zoom lens barrel is provided having a plurality of lens groups which are moved with respect to one another along a predetermined path. The zoom lens barrel comprises a driving barrel which rotates about an optical axis of the plurality of lens groups and at least three telescoping barrels which are moved in the direction of the optical axis by rotation of the driving barrel. Each telescoping barrel which is mounted on an inner periphery of another telescoping barrel of the telescoping barrels, travels a greater distance along the optical axis direction than the another telescoping barrel. A lens group driving mechanism is provided for moving the plurality of lens groups in the optical axis direction by movement of the at least three telescoping barrels in the optical axis direction.
