摘要： A zoom lens barrel assembly includes a plurality of lens barrels including a rearmost lens barrel, secured to a camera body, and a frontmost lens barrel. At least one adjacent pair of lens barrels are connected to each other via a helicoid structure. The frontmost lens barrel and a first adjacent lens barrel are connected to each other via a cam structure. The helicoid structure allows the adjacent pair of the lens barrels to rotate and move in an optical axis direction relative to each other while the zoom lens barrel assembly moves from a retracted position to a minimally extended position for a photographing operation. At least a portion of the helicoid structure includes a slip region which allows the pair of adjacent lens barrels to rotate without relatively moving along the optical axis.
