Abstract
The present disclosure discloses an optical imaging lens group. The optical imaging lens group comprises, 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, a seventh lens and an eighth lens, wherein the first lens, the second lens, the third lens, the fourth lens, the fifth lens, the sixth lens, the seventh lens and the eighth lens have refractive powers. At least one lens in the first lens to the eighth lens has a non-rotationally symmetric aspheric surface; a total effective focal length fy of the optical imaging lens group in a Y-axis direction and a total effective focal length fx of the optical imaging lens group in an X-axis direction satisfy: fy/fx<0.8; and an f-number Fnoy of the optical imaging lens group in the Y-axis direction satisfies: Fnoy<2.9.
