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 and a fifth lens. The first lens has a positive refractive power, an object-side surface of the first lens is a convex surface, and an image-side surface of the first lens is a concave surface. The second lens has a positive refractive power or a negative refractive power. The third lens has a negative refractive power. The fourth lens has a positive refractive power. The fifth lens has a negative refractive power, and an image-side surface of the fifth lens is a convex surface. A total effective focal length f of the optical imaging lens assembly and an entrance pupil diameter EPD of the optical imaging lens assembly satisfy: f/EPD≤1.9.
