Abstract

The present disclosure discloses an optical imaging lens assembly including, sequentially from an object side to an image side along an optical axis, a first lens having positive refractive power; a second lens having negative refractive power; a third lens having refractive power; a fourth lens having refractive power; a fifth lens having refractive power with a convex object-side surface; a sixth lens having positive refractive power with a convex object-side surface a convex image-side surface; and a seventh lens having negative refractive power, wherein a distance TTL along the optical axis from an object-side surface of the first lens to an imaging plane of the optical imaging lens assembly and half of a diagonal length ImgH of an effective pixel area on the imaging plane of the optical imaging lens assembly satisfy ImgH/(TTL/ImgH)>5.0 mm.
