  • Publication number: 20110096413
    Abstract: A five-lens image lens system is revealed. The five-lens image lens system includes a first lens group with a negative power and a second lens group with a positive power. Along an optical axis in order from an object plane to an image plane, the first lens group includes a negative first lens and a negative second lens while at least one of optical surfaces of the first lens and the second lens is an aspherical optical surface. The second lens group includes a positive third lens, a positive fourth lens, and a negative fifth lens from the object plane to the image plane while an image-side lens surface of the positive fourth lens is glued with an object-side lens surface of the negative fifth lens.
