Abstract

The disclosure discloses an optical imaging lens assembly, which sequentially includes, from an object side to an image side along an optical axis, a first lens, a second lens, a third lens, a fourth lens and a fifth lens with refractive power respectively, wherein TTL is a distance from an object-side surface of the first lens to an imaging surface of the optical imaging lens assembly on the optical axis, and ImgH is a half of a diagonal length of an effective pixel region on the imaging surface of the optical imaging lens assembly, TTL and ImgH meet TTL/ImgH<1.5; and a sum fp of effective focal lengths of the lenses with positive refractive power in the first lens to the fifth lens and a sum fm of effective focal lengths of the lenses with negative refractive power in the first lens to the fifth lens meet −19.0<fm/fp<−10.0.
