Image capturing lens assembly and image capturing device

摘要

An image capturing lens assembly includes, 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, a fifth lens element and a sixth lens element. The first lens element with positive refractive power has an object-side surface being convex in a paraxial region thereof. The second lens element has negative refractive power. The third lens element has refractive power. The fourth lens element has refractive power. The fifth lens element with refractive power has two surfaces being both aspheric, wherein at least one of the surfaces of the fifth lens element has at least one inflection point thereon. The sixth lens element with positive refractive power has an image-side surface being convex in a paraxial region thereof, wherein the surfaces of the sixth lens element are both aspheric.
