Claim 0:
1. 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 and a sixth lens, each of which has refractive power,
wherein,
an object-side surface of the first lens is a convex surface, and an image-side surface of the first lens is a concave surface;
an image-side surface of the second lens is a concave surface; and
an object-side surface of the sixth lens is a convex surface,
wherein 1≤f5/f1≤3.5, and
TTL/ImgH≤1.3,
where f1 is an effective focal length of the first lens, f5 is an effective focal length of the fifth lens, TTL is a distance along the optical axis from the object-side surface of the first lens to an imaging plane of the optical imaging lens assembly, and ImgH is half of a diagonal length of an effective pixel area on the imaging plane of the optical imaging lens assembly.
