OPTICAL PHOTOGRAPHING LENS ASSEMBLY, IMAGE CAPTURING DEVICE AND MOBILE TERMINAL

摘要

An optical photographing 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 and a fifth lens element. The first lens element has refractive power. The second lens element has positive refractive power. The third lens element with positive refractive power has an image-side surface being concave in a paraxial region thereof. The fourth lens element has refractive power. The fifth lens element with refractive power has an image-side surface being concave in a paraxial region thereof, wherein an object-side surface and the image-side surface of the fifth lens element are aspheric, and at least one of the surfaces of the fifth lens element has at least one inflection point. The optical photographing lens assembly has a total of five lens elements with refractive power.
