Camera optical lens

Abstract

A camera optical lens includes first to eighth lenses that are arranged sequentially from an object side to an image side. At least one of the first lens to the eighth lens has a free-form surface, and the camera optical lens satisfies: 1.30≤f4/f≤5.00; and 0≤(R9+R10)/(R9−R10)≤4.50, where f denotes a focal length of the camera optical lens, f4 denotes a focal length of the fourth lens, R9 denotes a curvature radius of an object-side surface of the fifth lens, and R10 denotes a curvature radius of an image-side surface of the fifth lens. The camera optical lens has a wide angle and is ultra-thin, as well as having excellent optical performance, and can effectively correct aberration and improve the performance of the optical system.
