Abstract

The present disclosure provides an optical imaging lens assembly including, sequentially from an object side to an image side along an optical axis, a first lens having a positive refractive power; a second lens having a positive refractive power; a third lens having a negative refractive power; a fourth lens having a refractive power, an object-side surface thereof being a concave surface, and an image-side surface thereof being a convex surface; a fifth lens having a refractive power; a sixth lens having a positive refractive power, an object-side surface thereof being a concave surface, and an image-side surface thereof being a convex surface; and a seventh lens having a refractive power. An effective focal length f of the optical imaging lens assembly and an entrance pupil diameter of the optical imaging lens assembly satisfy f/EPD<1.5.
