Patent ID: 8456757

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; a third lens element with positive refractive power having a convex object-side surface and a concave image-side surface, wherein at least one of the object-side surface and the image-side surface of the third lens element is aspheric; a fourth lens element with positive refractive power made of plastic material, and having a concave object-side surface and a convex image-side surface, wherein at least one of the object-side surface and the image-side surface of the fourth lens element is aspheric; and a fifth lens element with refractive power made of plastic material, and having a convex image-side surface, wherein at least one of the object-side surface and the image-side surface of the fifth lens element is aspheric; wherein a focal length of the image capturing optical lens assembly is f, a focal length of the third lens element is f3, and a focal length of the fourth lens element is f4, the following relationships are satisfied: 0 <f/f 3<1.2; and 0.3< f 4 /f< 0.65.
