Patent ID: 8462446

Claim:
An optical imaging lens assembly comprising five lens elements with refractive power, 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 having a concave image-side surface; a third lens element with negative refractive power; a fourth lens element having a convex object-side surface and a concave image-side surface, and at least one of the object-side and image-side surfaces thereof being aspheric; and a fifth lens element having a concave image-side surface, at least one of the object-side and image-side surfaces thereof being aspheric, and at least one inflection point is formed on at least one of the object-side and image-side surfaces thereof; wherein a focal length of the second lens element is f2, a focal length of the third lens element is f3, the optical imaging lens assembly further comprises an aperture stop, a distance on an optical axis between the aperture stop and an 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, and they satisfy the relation: 0 <f 2 /f 3<1.7; and 0.65 <SL/TTL< 0.92.
