Abstract:
1. An optical imaging lens assembly comprising, in order from an object side to an image side: a first lens element having positive refractive power; a second lens element having positive refractive power; a third lens element having positive refractive power; a fourth lens element with positive refractive power having a convex image-side surface; and a fifth lens element with refractive power having a concave image-side surface in a paraxial region thereof, wherein the image-side surface of the fifth lens element has at least one convex shape in an off-axis region thereof, and an object-side surface and the image-side surface of the fifth lens element are aspheric; wherein the optical imaging lens assembly has a total of five lens elements with refractive power, a focal length of the optical imaging lens assembly is f, a curvature radius of the image-side surface of the fourth lens element is R8, and the following condition is satisfied:
