Abstract

Provided is an imaging lens assembly, including a first lens, a second lens, a third lens, a fourth lens and a fifth lens from an object side of the imaging lens assembly to an image side of the imaging lens assembly in turn. The first lens is of a positive focal power, an object side surface of the first lens is convex; the second lens is of a negative focal power, an image side surface of the second lens is concave; the third lens is of a focal power; the fourth lens is of a focal power; and the fifth lens is of a negative focal power; and a combined focal power of the third lens and the fourth lens is negative. The imaging lens assembly meets the following formulas: 2.0<f/ImgH<3.0; and 0<f1/f<0.5.
