Abstract
A photographing system lens assembly includes, in order from an object side to an image side: a first lens element, a second lens element, a third lens element and a fourth lens element. Each of the four lens elements has an object-side surface facing toward the object side and an image-side surface facing toward the image side. At least one surface of at least one lens element in the photographing system lens assembly has at least one inflection point. The first lens element has positive refractive power, the object-side surface of the first lens element is convex in a paraxial region thereof, and the image-side surface of the first lens element is convex in a paraxial region thereof. The object-side surface of the second lens element is concave in a paraxial region thereof. The image-side surface of the third lens element is concave in a paraxial region thereof.
