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, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens and a seventh lens. The first lens has negative refractive power; the second lens has negative refractive power; the third lens has positive refractive power; the fourth lens has positive refractive power; the fifth lens has refractive power, and an object-side surface thereof is a concave surface; the sixth lens has refractive power; and the seventh lens has negative refractive power. An effective focal length f1 of the first lens and a total effective focal length f of the optical imaging lens assembly satisfy −3.5<f1/f<0.
