发明名称 Photographing optical lens assembly
摘要 This invention provides a photographing optical lens assembly including, in order from an object side toward an image side: a first lens element with positive refractive power having a convex object-side surface, a second lens element with negative refractive power having a concave object-side surface and a concave image-side surface, a third lens element with positive refractive power, a fourth lens element with negative refractive power having a convex object-side surface and a concave image-side surface, and at least one of surfaces thereof being aspheric, a plastic fifth lens element having a convex object-side surface and a concave image-side surface with at least one inflection point. An aperture stop is positioned between an imaged object and the third lens element. The photographing optical lens assembly further comprises an electronic sensor on which the object is imaged.
