Optical imaging lens assembly

An optical imaging lens assembly, sequentially comprising, from an object side to an image side along an optical axis:

• a first lens with a negative refractive power,
• a second lens with a refractive power,
• a third lens with a refractive power,
• a fourth lens with a positive refractive power,
• a fifth lens with a refractive power,
• a sixth lens with a refractive power,
• a seventh lens with a positive refractive power,
• an eighth lens with a negative refractive power, and
• a ninth lens with a negative refractive power,
• wherein ImgH is a half of a diagonal length of an effective pixel region on an imaging surface of the optical imaging lens assembly, ImgH and a total effective focal length f of the optical imaging lens assembly meet 1.2<ImgH/f<2.2;
• and
• there is a spacing distance between any two adjacent lenses in the first lens to the ninth lens;
• a combined focal length f56 of the fifth lens and the sixth lens, a combined focal length f12 of the first lens and the second lens and a combined focal length f89 of the eighth lens and the ninth lens meet 0.8<f56/(f12+f89)<2.9.
