Abstract

Provided is a camera optical lens including, sequentially from an object side to an image side: a first lens having a positive refractive power; a second lens having a negative refractive power; a third lens having a negative refractive power; a fourth lens having a positive refractive power; and a fifth lens having a negative refractive power. The camera optical lens satisfies following conditions: 0.75≤f1/f≤0.86; −0.30≤f1/f2≤−0.20; 1.30≤(f1+f4)/f≤1.50; −22.00≤(f2+f3+f5)/f≤−9.00; and 0.05≤d8/f≤0.08, where f denotes a focal length of the camera optical lens; f1, f2, f3, f4 and f5 denote focal lengths of the first, second, third, fourth, and fifth lenses, respectively; 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 ultra-thin, wide-angle lenses having large apertures.
