Abstract
A camera optical lens includes, from an object side to an image side: a first lens with a negative refractive power, a second lens, a third lens with a positive refractive power, and a fourth lens with a negative refractive power. The camera optical lens satisfies the conditions of −5.00≤f1/f≤−2.00, 0.40≤f3/f≤0.70, −1.20≤f4/f≤−0.80, 2.50≤(R3+R4)/(R3−R4)≤20.00, and 1.20≤d1/d2≤3.50. The camera optical lens of the present disclosure has excellent optical performances, and meanwhile can meet design requirements of a wide-angle and ultra-thin.
