Abstract
The present application discloses an optical imaging lens group, including 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 having refractive powers in order from an object side to an image side along an optical axis. The first lens has a negative refractive power. The fourth lens has a positive refractive power. The eighth lens has a negative refractive power. At least one of the first lens to the eighth lens has a non-rotationally symmetrical aspherical lens surface, and the maximum TV distortion TDT in an imaging range of the optical imaging lens group satisfies: |TDT|≤3.5%.
