Claim 0:
1. An optical imaging lens assembly, sequentially comprising, from an object side to an image side along an optical axis:
a first lens with a positive refractive power;
a second lens;
a third lens with a positive refractive power;
a fourth lens;
a fifth lens with a positive refractive power; and
a sixth lens with a negative refractive power,
wherein a total effective focal length f of the optical imaging lens assembly and an entrance pupil diameter (EPD) of the optical imaging lens assembly meet:

f/EPD<1.35; and

an effective focal length f3 of the third lens, an effective focal length f5 of the fifth lens and an effective focal length f1 of the first lens meet:

0.9<(f3+f5)/f1<1.7.
