Claim:
1. A photographing optical lens assembly comprising, in order from an object side to an image side: a first lens element with negative refractive power having a concave image-side surface; a second lens element with negative refractive power having a concave image-side surface; a third lens element having positive refractive power; a fourth lens element with positive refractive power having a convex image-side surface, wherein an object-side surface and the image-side surface of the fourth lens element are both aspheric; and a fifth lens element with negative refractive power having a concave object-side surface and a convex image-side surface, wherein the object-side surface and the image-side surface of the fifth lens element are both aspheric; wherein the photographing optical lens assembly has a total of five lens elements, an axial distance between the first lens element and the second lens element is T
