Patent ID: 8284291

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; a second lens element with negative refractive power; a third lens element; a fourth lens element; and a fifth lens element having a concave image-side surface and made of plastic material, wherein the fifth lens element has at least one inflection point formed on at least one of the object-side surface and the image-side surface thereof; wherein a focal length of the photographing optical lens assembly is f, a focal length of the first lens element is f 1 ; the photographing optical lens assembly further comprises an aperture stop and an image sensor, wherein a distance on the optical axis between the aperture stop and the image plane is SL; a distance on the optical axis between the object-side surface of the first lens element and the image plane is TTL, when the incident angle θ 1 of the light is 36 degrees and the light passes through the center of the aperture stop, the vertical distance from the optical axis to the intersection point of the light and the image-side surface of the fifth lens element is Yc 1 , the image sensor is located on the image plane, a half of a diagonal length of an effective pixel area of the image sensor is ImgH, and they satisfy the following relationships: 0.7 <f/f 1<2.0; 0.7 <SL/TTL< 1.2; and 0.3 <Yc 1/ ImgH< 0.9.
