A wide-angle optical lens assembly comprises, in order from an object side to an image side: a first lens element with a negative refractive power having concave image-side surface, a second lens element with a positive refractive power, a third lens element with a positive refractive power, and a fourth lens element with a positive refractive power having convex image-side surface, at least one surface of the fourth lens element thereof being aspheric. By such arrangement, total track length and photosensitivity of the wide-angle optical lens assembly can be effectively reduced while retaining large field of view and superb image quality. |
