Abstract: From an object plane to an image plane along an optical axis, a camera lens including a first lens, a diffractive optical element and a lens module is provided in various embodiments. The first lens has a positive focal power. The diffractive optical element has a positive focal power and a negative dispersion property. A surface that is of the diffractive optical element or the first lens and that faces the object plane side is a convex surface at the optical axis, a surface that is of the diffractive optical element or the first lens and that faces the image plane side is a concave surface at the optical axis. The lens module includes N lenses. At least one of a surface facing the object plane side and a surface facing the image plane side that are of each of the N lenses is an aspheric surface.
