Abstract
A camera optical lens includes a first lens, a second lens, a third lens, a fourth lens, and a fifth lens that are sequentially arranged from an object side to an image side. The camera optical lens satisfies following conditions: 0.50≤d2/d3≤2.00; −4.00≤R1/R2≤−1.50; and −8.00≤f3/f≤−4.00, where f denotes a focal length of the camera optical lens; f3 denotes a focal length of the third lens; R1 denotes a curvature radius of an object side surface of the first lens; R2 denotes a curvature radius of the image side surface of the first lens; d2 denotes an on-axis distance from an image side surface of the first lens to an object side surface of the second lens; and d3 denotes an on-axis thickness of the second lens. The camera optical lens has good optical performance while satisfying design requirements for ultra-thin, wide-angle lenses having large apertures.
