Abstract
A photographing lens assembly includes five lens elements which are, in order from an object side to an image side along an optical path, a first lens element, a second lens element, a third lens element, a fourth lens element and a fifth lens element. Each of the five lens elements has an object-side surface facing toward the object side and an image-side surface facing toward the image side. The first lens element has positive refractive power. The third lens element has negative refractive power, the object-side surface of the third lens element is convex in a paraxial region thereof, and the image-side surface of the third lens element is concave in a paraxial region thereof. At least one of the object-side surface and the image-side surface of at least one lens element of the photographing lens assembly is aspheric.
