Abstract:
An photographing optical lens assembly includes, in order from an object side to an image side, a first lens element with negative refractive power including a convex object-side surface, a second lens element with positive refractive power, 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 includes a concave object-side surface and a convex image-side surface, and a fifth lens element with positive refractive power including an image-side surface, an object-side surface and at least one inflection point. At least one of the object-side surface and the image-side surface of the fifth lens element is 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.
