Classification: CPC G | IPC G

Claim 0:
1. An optical imaging lens assembly, sequentially from an object side to an image side of the optical imaging lens assembly along an optical axis, comprising:
a first lens having refractive power, an object-side surface of the first lens is a concave surface, and an image-side surface of the first lens is a convex surface;
a second lens having refractive power;
a third lens having refractive power;
a fourth lens having refractive power;
a fifth lens having negative refractive power, and an object-side surface of the fifth lens is a concave surface;
a sixth lens having positive refractive power; and
a seventh lens having refractive power,
wherein f3/f>1.49, where f is a total effective focal length of the optical imaging lens assembly, and f3 is an effective focal length of the third lens.
