Abstract
The present disclosure discloses a camera lens assembly. The camera lens assembly includes, sequentially along an optical axis from an object side to an image side, a first lens, a second lens, a third lens, a fourth lens, and a fifth lens. The first lens has a positive refractive power, an object-side surface of the first lens is a convex surface, and an image-side surface of the first lens is a concave surface. Each of the second lens and the third lens has a positive refractive power or a negative refractive power. The fourth lens has a positive refractive power, and an image-side surface of the fourth lens is a convex surface. The fifth lens has a negative refractive power, and an object-side surface of the fifth lens is a concave surface. An effective semi-diameter DT52 of an image-side surface of the fifth lens and half of a diagonal length ImgH of an effective pixel area on an image plane of the camera lens assembly satisfy: 0.75<DT52/ImgH<1.
