Abstract

The application discloses an optical imaging lens assembly including, sequentially from an object side to an image side, a first lens with a positive refractive power and a concave image side surface; a second lens with a negative refractive power and a convex object side surface; a third lens with a refractive power and a convex image side surface; a fourth lens with a negative refractive power and a concave object side surface; a fifth lens with a positive refractive power and a convex image side surface; a sixth lens with a refractive power; and a seventh lens with a negative refractive power, wherein an effective focal length f of the optical imaging lens assembly, an entrance pupil diameter EPD of the optical imaging lens assembly and a space interval T67 between the sixth lens and the seventh lens satisfy f/EPD≤1.80, and 5.5<f/T67<11.5.
