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 refractive power; a second lens having refractive power; a third lens having negative refractive power; a fourth lens having refractive power and a convex object-side surface; a fifth lens having refractive power and a concave object-side surface; a sixth lens having refractive power; a seventh lens having refractive power; and an eighth lens having refractive power. A total effective focal length f of the optical imaging lens assembly and half of a maximal field-of-view Semi-FOV of the optical imaging lens assembly satisfy: f*tan(Semi-FOV)>5.5 mm. A total effective focal length f of the optical imaging lens assembly and an effective focal length f1 of the first lens satisfy: 0.5<f/f1<1.5.
