Claim 5:
6. An optical imaging lens assembly, sequentially from an object side to an image side along an optical axis, comprising: a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, a seventh lens and an eighth lens, each of which has refractive power,
wherein,
the first lens has positive refractive power;
the third lens has positive refractive power, and each of an object-side surface and an image-side surface of the third lens is a convex surface;
an object-side surface of the sixth lens is a convex surface; and
the eighth lens has negative refractive power, and an object-side surface of the eighth lens is a concave surface,
1.7<f1/f3<3, where f1 is an effective focal length of the first lens, and f3 is an effective focal length of the third lens.
