1. A camera module, comprising:
an optical imaging system comprising a first lens, a second lens, a third lens, a fourth lens, and a fifth lens having a concave image-side surface at an optical axis thereof, and
wherein the first to fifth lenses are sequentially disposed from an object side to an imaging plane,
wherein the optical imaging system has a total number of five lenses with refractive power,
wherein 75 degrees<FOV, where FOV is a field of view of the optical imaging system,
wherein a thickness of the first lens is greater than a thickness of the fifth lens, and
wherein a radius of curvature of an object-side surface of the fourth lens is less than a radius of curvature of an image-side surface of the third lens.
