Camera optical lens
The present invention relates to the technical field of optical lens and discloses a camera optical lens. The camera optical lens includes, 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 positive refractive power, and a fourth lens having a negative refractive power. The camera optical lens satisfies following conditions: −3.50≤f2/f≤−1.50; 3.00≤(R3+R4)/(R3−R4)≤8.00; 8.00≤d1/d2≤15.00; 0.50≤f3/f≤0.75; −5.00≤R2/R1≤−2.50; −0.70≤f4/f≤−0.40. The camera optical lens can achieve excellent optical characteristics with a large aperture, wide-angle, and being ultra-thin.
