Abstract
The present disclosure discloses a camera optical lens. The camera optical lens includes, from an object side to an image side, a first lens with a positive refractive power; a second lens with a negative refractive power; a third lens with a negative refractive power; a fourth lens with a positive refractive power; and a fifth lens with a negative refractive power. The camera optical lens satisfies the following conditions: 0.40≤f1/f≤0.70; 2.00≤(R5+R6)/(R5−R6)≤20.00; 1.20≤d4/d5≤5.00 and −15.00≤R7/R8≤−1.50. The camera optical lens of the present disclosure has excellent optical performances, and meanwhile can meet design requirements of a large aperture, a long focal length and ultra-thin.
