Classification: CPC G | IPC G

Claim 0:
1. A camera optical lens, comprising, 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 at least one of the first lens, the second lens, the third lens, the fourth lens, the fifth lens, the sixth lens, the seventh lens, or the eighth lens has a free-form surface, and
wherein the camera optical lens satisfies:

0.80≤f6/f5≤3.00;

5.00≤d7/d6≤22.00; and

−6.00≤R12/R11≤−2.50,

where f5 denotes a focal length of the fifth lens, f6 denotes a focal length of the sixth lens, d6 denotes an on-axis distance from an image-side surface of the third lens to an object-side surface of the fourth lens, d7 denotes an on-axis thickness of the fourth lens, R11 denotes a central curvature radius of an object-side surface of the sixth lens, and R12 denotes a central curvature radius of an image-side surface of the sixth lens.
