Abstract
An image capturing optical lens system includes four 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 and a fourth lens element. The first lens element has an object-side surface being convex in a paraxial region thereof. The third lens element with positive refractive power has an object-side surface being convex in a paraxial region thereof and an image-side surface being concave in a paraxial region thereof. The fourth lens element has negative refractive power.
