摘要：

This invention provides a photographing optical lens system in order from an object side to an image side including: a first lens element with positive refractive power having a convex object-side surface, a second lens element with positive refractive power having a convex image-side surface, a third lens element with positive refractive power having a convex object-side surface and a concave image-side surface, both the two surfaces being aspheric and at least one of them having at least one inflection point formed thereon; wherein the photographing optical lens system further comprises an aperture stop configured between an imaged-object and the second lens element, and there are three lens elements with refractive power.
