Abstract
The present disclosure provides a camera lens assembly, the camera lens assembly including sequentially, from an object side to an image side along an optical axis, a first lens having a negative refractive power, wherein an image-side surface of the first lens is a concave surface; a second lens, wherein an image-side surface of the second lens is a convex surface; a third lens; a fourth lens having a negative refractive power; and at least one subsequent lens. An effective radius DT21 of an object-side surface of the second lens and an effective radius DT42 of an image-side surface of the fourth lens satisfy: 0.5<DT21/DT42<1.
