Imaging lens system, image capturing unit and electronic device

Abstract

An imaging lens system includes six 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, a fifth lens element and a sixth lens element. The first lens element has positive refractive power. The second lens element with positive refractive power has an image-side surface being convex in a paraxial region thereof. The third lens element with negative refractive power has an object-side surface being concave in a paraxial region thereof and an image-side surface being convex in a paraxial region thereof. The fifth lens element with positive refractive power has an object-side surface being convex in a paraxial region thereof. The sixth lens element with negative refractive power has an object-side surface being convex in a paraxial region thereof and having at least one inflection point and an image-side surface being concave in a paraxial region thereof.
