Abstract
An optical imaging lens system 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 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 image-side surface of the fourth lens element is concave in a paraxial region thereof. The object-side surface of the fifth lens element is convex in a paraxial region thereof, and the image-side surface of the fifth lens element is concave in a paraxial region thereof.
