Abstract: An imaging lens system includes five lens elements, which are, in order from an object side to an image side: a first lens element, a second lens element, a third lens element, a fourth lens element and a fifth lens element. At least one of an object-side surface and an image-side surface of the fifth lens element has at least one inflection point. The object-side surface and the image-side surface of the fifth lens element are both aspheric.
