A retractable zoom lens includes a holder, at least one movable barrel assembly received in the holder, a holding frame received in the movable barrel assembly, and a slide barrel engaged with the holding frame. The holding frame can move along the optical axis along with the movement of the movable barrel assembly. The movable barrel assembly is movable along an optical axis of the retractable zoom lens, and the slide barrel is slidable along a direction substantially perpendicular to the optical axis during an object image captured by an image pickup device of the retractable zoom lens.
