Abstract
The disclosure provides an optical imaging lens assembly, which sequentially includes from an object side to an image side along an optical axis: a first lens with a positive refractive power; a second lens with a refractive power; a third lens with a refractive power; a fourth lens with a refractive power; a fifth lens with a refractive power, an object-side surface thereof is a convex surface, and an image-side surface thereof is a concave surface; a sixth lens with a positive refractive power, an object-side surface thereof is a convex surface, and an image-side surface thereof is a concave surface; a seventh lens with a negative refractive power; wherein an on-axis distance TTL from an object-side surface of the first lens to an imaging surface and a half of a diagonal length ImgH of an effective pixel region on the imaging surface satisfy: TTL/ImgH<1.25.
