Claim 9:
10. 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 -−4.0<f6/(f2+f8)<−2.5, and
1.5<(R5+R6)/f<2.5,
where f2 is an effective focal length of the second lens, f6 is an effective focal length of the sixth lens, f8 is an effective focal length of the eighth lens, R5 is a radius of curvature of an object-side surface of the third lens, R6 is a radius of curvature of an image-side surface of the third lens, and f is a total effective focal length of the optical imaging lens assembly, and
wherein 2.0<(T67+T78)/(CT7+CT8)<3.5,
where T67 is a spaced interval between the sixth lens and the seventh lens along the optical axis, T78 is a spaced interval between the seventh lens and the eighth lens along the optical axis, CT7 is a center thickness of the seventh lens along the optical axis, and CT8 is a center thickness of the eighth lens along the optical axis.
