Patent ID: 7821724

Claim:
A photographing optical lens assembly comprising, in order from an object side to an image side: a first lens element with positive refractive power having a convex object-side surface and a concave image-side surface, the object-side and image-side surfaces thereof being aspheric; a second lens element with negative refractive power having a concave object-side surface and a convex image-side surface, the object-side and image-side surfaces thereof being aspheric; and an aperture stop located in front of the first lens element; wherein an Abbe number of the first lens element is V 1 , an Abbe number of the second lens element is V 2 , and they satisfy the relation: |V 1 −V 2 |<15; and wherein the number of the lens elements with refractive power of the photographing optical lens assembly is limited to two.
