Patent ID: 8848298

Claim:
An image capturing 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; a second lens element with negative refractive power; a third lens element with negative refractive power having a concave object-side surface and a convex image-side surface; and a fourth lens element with refractive power having a convex object-side surface and a concave image-side surface, wherein the object-side surface and the image-side surface of the fourth lens element are aspheric, and the fourth 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 image capturing optical lens assembly is f, a focal length of the third lens element is f3, an axial distance between the first lens element and the second lens element is T12, an axial distance between the third lens element and the fourth lens element is T34, the Abbe number of the second lens element is V2, the Abbe number of the third lens element is V3, and the following relationships are satisfied: −1.2 <f/f 3<−0.3; 0 <T 34/ T 12<2.1; and 23 <V 3 −V 2<42.
