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 image-side surface; a third lens element with positive refractive power having a convex image-side surface, wherein an object-side surface and the image-side surface of the third lens element are aspheric; a fourth lens element with positive refractive power, wherein an object-side surface and an image-side surface of the fourth lens element are aspheric; and fifth lens element with refractive power made of plastic material and having a concave image-side surface, wherein an object-side surface and the 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 first lens element is f 1 , a focal length of the third lens element is f 3 , a curvature radius of the image-side surface of the second lens element is R 4 , a curvature radius of the image-side surface of the third lens element is R 6 , an axial distance between the second lens element and the third lens element is T 23 , a central thickness of the fifth lens element is CT 5 , and the following relationships are satisfied: 0<( f/f 3)−( f/f 1)<0.85: 0 <R 4 /f< 3.0; −4.5 <R 6 /f< 0; and 0 <T 23/CT5<0.70.
