An image capturing lens assembly comprises, 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 with refractive power, a third lens element with positive refractive power having a convex image-side surface, and a fourth lens element with refractive power having a convex object-side surface and a concave image-side surface. The object-side surface and the image-side surface of the fourth lens element are aspheric and have at least one inflection point.
