A miniaturized optical lens system comprises, in order from the object side to the image side: a first lens element with positive refractive power having a convex object-side surface, a concave image-side surface and one of the surfaces being aspheric; and a second lens element with negative refractive power having a concave object-side surface, a convex image-side surface and one of the surfaces being aspheric. The optical lens system is further provided with an aperture stop. Such arrangements can effectively reduce the volume of the optical lens system, correct aberrations and astigmatism of the system in order to obtain higher image quality.
