Abstract: A zoom lens barrel driving system for a camera includes a driving source, a magnification controlling unit, and a focus controlling unit. The magnification controlling unit is formed with a plurality of barrels and a plurality of lens groups. The barrels and the lens groups move in an optical axis direction upon receipt of a driving power from the driving source such that magnification continuously varies. The focus controlling unit is formed by the lens groups. The lens groups repeatedly move between a near focal position and an infinite focal position in the optical axis direction in synchronization with variation in the magnification to perform a focus controlling operation.
