Abstract
An optical imaging lens assembly is provided, along an optical axis from an object side to an image side, sequentially includes: a first lens having refractive power; an autofocus assembly; a second lens having refractive power, and an image-side surface of the second lens being a concave surface; a third lens having refractive power, and an image-side surface of the third lens being a convex surface; a fourth lens having refractive power, an object-side surface of the fourth lens being a concave surface, and an image-side surface of the fourth lens being a convex surface; and at least one subsequent lens having refractive power. A radius of curvature of an object-side surface of the autofocus assembly being variable.
