1. An optical imaging lens assembly, 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, which are sequentially arranged from an object side to an image side of the optical imaging lens assembly along an optical axis,
wherein,
each of the first lens to the eighth lens has refractive power,
at least one of the first lens to the eighth lens has an aspheric surface,
wherein TTL/f≤1.0,
ImgH≥6.0 mm,
1.0<TTL/ImgH<1.5, and
−4.0<f6/(f2+f8)<−2.5
where TTL is a distance along the optical axis from an object-side surface of the first lens to an imaging plane of the optical imaging lens assembly, f is a total effective focal length of the optical imaging lens assembly, ImgH is half of a diagonal length of an effective pixel area on the imaging plane of the optical imaging lens assembly, f2 is an effective focal length of the second lens, f6 is an effective focal length of the sixth lens, and f8 is an effective focal length of the eighth lens.
