Claim 11:
12. 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 refractive power and a convex image-side surface;
the fourth lens has refractive power and a concave object-side surface;
the fifth lens has refractive power;
the sixth lens has positive refractive power; and
the seventh lens has negative refractive power;
wherein 0.8<CT3/(CT2+CT4)<1.2,
where CT3 is a center thickness of the third lens along the optical axis, CT2 is a center thickness of the second lens along the optical axis, and CT4 is a center thickness of the fourth lens along the optical axis.
