Abstract
A camera optical lens includes first to fifth lenses that are sequentially arranged from an object side to an image side. Each of the first lens, the third lens, and the fourth lens has a positive refractive power, and each of the second lens and the fifth lens has a negative refractive power. The camera optical lens satisfies: 0.50≤f1/f≤0.80; −1.20≤f2/f≤−0.70; 1.50≤d8/d9≤3.00; −1.50≤R3/R4≤−0.60; and 1.20≤R7/R8≤2.00, where f denotes a focal length of the camera optical lens; f1 denotes a focal length of the first lens; f2 denotes a focal length of the second lens; and d8 denotes an on-axis distance from an image-side surface of the fourth lens to an object-side surface of the fifth lens. The camera optical lens can achieve high optical performance while satisfying design requirements for being ultra-thin and having a wide-angle and a large aperture.
