Abstract

An optical imaging lens assembly is provided. The optical imaging lens assembly includes, sequentially along an optical axis from an object side to an image side, 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 a positive refractive power, the second lens and the seventh lens have a negative refractive power, and the third, fourth, fifth, and sixth lenses have a positive refractive power or a negative refractive power. Object-side surfaces of the first lens and the second lens are a convex surface, object-side surfaces of the fourth lens and the seventh lens are a concave surface, and image-side surfaces of the first, second, and seventh lens are a concave surface. A total effective focal length f and an entrance pupil diameter EPD of the optical imaging lens assembly satisfy: f/EPD≤1.70.
