Abstract
A photographing optical lens assembly includes, 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 convex image-side surface, and a second lens element with positive refractive power having a concave object-side surface and a convex image-side surface. At least one surface of the first lens element is aspheric and two surfaces of the second lens element are aspheric. The photographing optical lens assembly can also include a stop and an image plane. By adjusting the thicknesses of the first lens element and the second lens element as well as the allocation of the stop in the photographing optical lens assembly can effectively reduce the size as well as the sensitivity of the photographing optical lens assembly while gaining superior resolution.
