Abstract:
1. 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 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 f3, an axial distance between the first lens element and the second lens element is T
