Abstract:
1. A photographing 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 having a concave object-side surface and a convex image-side surface, the object-side and image-side surfaces thereof being aspheric; a third lens element with negative refractive power having a convex object-side surface and a concave image-side surface, the object-side and image-side surfaces thereof being aspheric, and at least one inflection point being formed on the image-side surface; wherein the lens assembly is further provided with an electronic sensor disposed at an image plane for image formation of an object, and a stop disposed between the object and the first lens element; wherein a distance on an optical axis between the first lens element and the second lens element is T
