Abstract:
1. An image capturing lens system comprising five lens elements with refractive power, in order from an object side to an image side: a first lens element with positive refractive power having a convex object-side surface; a second lens element having positive refractive power; a third lens element having negative refractive power; a fourth lens element with refractive power having a concave image-side surface in a paraxial region thereof, wherein an object-side surface and the image-side surface of the fourth lens element are aspheric; and a fifth lens element with refractive power having a concave image-side surface in a paraxial region thereof, wherein the image-side surface of the fifth lens element has at least one inflection point, and an object-side surface and the image-side surface of the fifth lens element are aspheric; wherein the image capturing lens system has a total of five lens elements with refractive power; and wherein a focal length of the first lens element is fl, a focal length of the third lens element is f
