Abstract
The present disclosure discloses an optical imaging lens assembly. The optical imaging lens assembly includes, sequentially along an optical axis from an object side to an image side, a first lens to a fifth 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, an object-side surface thereof is a convex surface, and an image-side surface thereof is a concave surface. The third lens has a positive refractive power or a negative refractive power. The fourth lens has a positive refractive power, and an object-side surface thereof is a concave surface. The fifth lens has a negative refractive power, and an image-side surface thereof is a convex surface. An effective focal length f1 of the first lens and an effective focal length f2 of the second lens satisfy: −0.9<f1/f2<−0.5.
