1. An optical imaging lens assembly, along an optical axis from an object side to an image side, sequentially comprising:
a first lens having positive refractive power;
a second lens having refractive power, and an object-side surface of the second lens being a convex surface;
a third lens having refractive power, an object-side surface of the third lens being a convex surface, and an image-side surface of the third lens being a convex surface;
a fourth lens having refractive power;
a radius of curvature R4 of an image-side surface of the second lens and a radius of curvature R8 of an image-side surface of the fourth lens satisfy: 3.0<R4/R8<4.5; and
half of a maximum field-of-view Semi-FOV of the optical imaging lens assembly and a maximum incident angle of a chief ray CRAmax of the optical imaging lens assembly to an electronic photosensitive component satisfying: 2.5<Tan(Semi−FOV+CRAmax)<3.5.
