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; a second lens element with negative refractive power having a concave object-side surface and a convex image-side surface; a third lens element with refractive power having a concave object-side surface, wherein the object-side surface and an image-side surface of the third lens element are aspheric; fourth lens element with positive refractive power, wherein an object-side surface and an image-side surface of the fourth lens element are aspheric; a fifth lens element with refractive power, 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 a focal length of the image capturing optical lens assembly is f, a focal length of the third lens element is f3, a focal length of the fifth lens element is f5, a curvature radius of the object-side surface of the fifth lens element is R9, a curvature radius of the image-side surface of the fifth lens element is R10, a curvature radius of the object-side surface of the second lens element is R3, a curvature radius of the image-side surface of the second lens element is R4, and the following relationships are satisfied: −1.75 <f/f 5<0.50; −1.3 <f/f 3<0.5; | R 10 /R 9|<1.0; and −1.39≦( R 3 +R 4)/( R 3 −R 4)<−1.0.
