Patent ID: 8390944

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, wherein the object-side surface of the first lens element and the image-side surface of the first lens element are convex, and at least one of the object-side and the image-side surfaces of the first lens element is aspheric; and a second lens element with positive refractive power, wherein the object-side surface of the second lens element is concave, the image-side surface of the second lens element is convex, and the object-side surface and the image-side surfaces of the second lens element are aspheric; wherein a thickness of the first lens element near an optical axis is CT 1 , an axial distance between the first lens element and the second lens element is T 12 , a thickness of the second lens element near the optical axis is CT 2 , a focal length of the photographing optical lens assembly is f, an Abbe number of the first lens element is V 1 , an Abbe number of the second lens element is V 2 , the photographing optical lens assembly further comprises a stop and an image plane, an axial distance between the stop and the image plane is SL, an axial distance between the object-side surface of the first lens element and the image plane is TTL, and the following conditions are satisfied: 0.25 <CT 2 /T 12 <0.80; 0.30 <CT 1 /f< 0.57; 20.0 <V 1 - V 2 <45.0; and 0.9 <SL/TTL< 1.2.
