Abstract
The present disclosure discloses an optical imaging lens assembly. The optical imaging lens assembly includes, sequentially from an object side to an image side along an optical axis, a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens and a seventh lens. The first lens has a positive refractive power, and an object-side surface thereof is a convex surface; the second lens has a negative refractive power, and an image-side surface thereof is a concave surface; each of the third lens, the fourth lens, the fifth lens and the sixth lens have a positive refractive power or a negative refractive power; the seventh lens has a negative refractive power, and an object-side surface thereof is a concave surface. A total effective focal length f of the optical imaging lens assembly and an effective focal length f1 of the first lens satisfy f/f1≥2.0.
