Claim 12:
13. An optical imaging lens assembly, sequentially comprising from an object side to an image side along an optical axis: a first lens, a second lens, a third lens, a fourth lens, a fifth lens, and a sixth lens with refractive power respectively, wherein
a curvature radius R9 of an object-side surface of the fifth lens and an abbe number V5 of the fifth lens satisfy −5.0 mm-1<V5/R9<−2.5 mm-1; and
a spacing distance T34 between the third lens and the fourth lens on the optical axis and a spacing distance T45 between the fourth lens and the fifth lens on the optical axis satisfy 4.0<T34/T45<15.5;
a curvature radius R2 of an image-side surface of the first lens and a curvature radius R3 of an object-side surface of the second lens satisfy 1.0<R3/R2<2.0.
