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 having a positive refractive power; a second lens having a negative refractive power; a third lens having a refractive power; a fourth lens having a refractive power; a fifth lens having a refractive power; a sixth lens having a refractive power, where an object-side surface of the sixth lens is a convex surface, and an image-side surface of the sixth lens is a convex surface; and a seventh lens having a negative refractive power, where an object-side surface of the seventh lens is a convex surface. An effective focal length f2 of the second lens and a total effective focal length f of the camera lens assembly satisfy: −3≤f2/f<−1.5.
