Claim Text:
1. An optical photographing lens assembly comprising, in order from an object side to an image side: a first lens element with positive refractive power having an image-side surface being concave in a paraxial region thereof; a second lens element having positive refractive power; a third lens element having an image-side surface being concave in a paraxial region thereof; a fourth lens element with positive refractive power having an object-side surface being concave in a paraxial region thereof and an image-side surface being convex in a paraxial region thereof; and a fifth lens element with negative refractive power having an object-side surface being convex in a paraxial region thereof and an image-side surface being concave in a paraxial region thereof, wherein both of the object-side surface and the image-side surface of the fifth lens element are aspheric, and at least one of the object-side surface and the image-side surface of the fifth lens element has at least one inflection point; wherein the optical photographing lens assembly has a total of five lens elements, an Abbe number of the fourth lens element is V4, an Abbe number of the fifth lens element is V5, and the following condition is satisfied:
