Abstract
A camera optical lens includes, 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. 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 the camera optical lens satisfies: 0.80≤f6/f5≤3.00; 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, 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. The camera optical lens has a large aperture, a wide angle, and ultra-thinness, as well as excellent optical performance.
