Abstract
A zoom lens includes a lens, a shutter-aperture, a moving barrel and a resisting ring. The lens includes a curved surface. The shutter-aperture includes a diaphragm for allowing light rays passing through and at least three blind holes. The moving barrel includes a bottom plate, a securing portion for securing the lens, at least three protrusions surrounding the securing portion and at least three elastic elements sleeved on the protrusions respectively. The securing portion and the at least three protrusions extend towards the object-side from the bottom plate. The resisting ring is disposed on an end of the moving barrel opposite to the bottom plate. The aperture-shutter is received in the moving barrel and the movement of the aperture-shutter is bounded by the resisting ring. When the zoom lens contracts, the protrusions are received in the blind holes correspondingly and the lens is received in the diaphragm.
