Patent ID: 8917458

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; a second lens element with negative refractive power; a third lens element with refractive power having a convex object-side surface, wherein the object-side surface and an image-side surface of the third lens element are aspheric; a fourth lens element with positive refractive power having a convex to object-side surface and a convex image-side surface; and a fifth lens element with negative refractive power which is made of plastic material, wherein an object-side surface and an image-side surface of the fifth lens element are aspheric, and 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 the image capturing optical lens assembly has a total of five lens elements with refractive power, a curvature radius of an object-side surface of the second lens element is R3, a curvature radius of an image-side surface of the second lens element is R4, a curvature radius of the object-side surface of the fourth lens element is R7, and a curvature radius of the image-side surface of the fourth lens element is R8, the following relationships are satisfied: 0<( R 3+ R 4)/( R 3− R 4)<3.0; and −3.3< R 7/ R 8<0.
