Abstract:
An photographing optical lens assembly includes, in order from an object side to an image side, a first lens element with refractive power including a convex object-side surface, a second lens element with positive refractive power including a convex image-side surface, a third lens element with positive refractive power including a concave object-side surface and a convex image-side surface, a fourth lens element with negative refractive power, and a fifth lens element with positive refractive power including a convex object-side surface, a concave image-side surface and at least one inflection point. The surfaces of the fifth lens element are aspheric. By adjusting the photographing optical lens assembly, the total length of the photographing optical lens assembly is reduced, the aberration is corrected, and the image quality is improved.
