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 to the eighth lens has a free-form surface, and the camera optical lens satisfies: −3.50≤f2/f1≤−1.50; and −2.00≤R9/R10≤−0.80, where f1 is a focal length of the first lens, f2 is a focal length of the second lens, R9 is a central curvature radius of an object side surface of the fifth lens, and R10 is a central curvature radius of an image side surface of the fifth lens. The camera optical lens has a large aperture, a wide angle, and ultra-thinness, as well as excellent optical performance.
