1. A camera lens assembly, comprising, sequentially from an object side to an image side along an optical axis, a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens and a seventh lens,
wherein,
the first lens has negative refractive power;
the second lens has positive refractive power and a concave image-side surface;
the third lens has positive refractive power and a convex image-side surface;
the fourth lens has refractive power;
the fifth lens has refractive power;
the sixth lens has positive refractive power; and
the seventh lens has negative refractive power,
wherein 2<f2/f<4.5, where f2 is an effective focal length of the second lens, and f is a total effective focal length of the camera lens assembly.
