Abstract
Provided is a camera optical lens including first to fifth lenses arranged from an object side to an image side. The camera optical lens satisfies following conditions: 0.95≤f2/f≤2.00; −2.80≤f3/f≤−1.50; 4.12≤(R1+R2)/(R1−R2)≤26.82; 3.20≤R7/R8≤6.00; and 1.80≤d3/d5≤3.50, where f, f2, and f3 respectively denote focal lengths of the camera optical lens, the second lens, and the third lens; R1 and R2 denote curvature radiuses of an object side surface and an image side surface of the first lens; R7 and R8 denote curvature radiuses of an object side surface and an image side surface of the fourth lens; d3 and d5 denote on-axis thicknesses of the second lens and the third lens. The camera optical lens has high optical performance while satisfying design requirements for ultra-thin, wide-angle lenses having large apertures.
