Camera optical lens

Abstract

The present disclosure discloses a camera optical lens including: a first lens having a positive refractive power; a second lens having a negative refractive power; a third lens having a positive power; a fourth lens having a negative refractive power, a fifth lens having a positive power; and a sixth lens having a negative refractive power; wherein the camera optical lens satisfies conditions: 0.35≤f1/f≤0.68; 2.00≤(R3+R4)/(R3−R4)≤5.00; 1.50≤d5/d7≤3.00; where f and f1 respectively denotes a focal length of the camera optical lens and the first lens; R3 and R5 respectively denotes a central curvature radius of an object-side surface and an image-side surface of the second lens; d5 and d7 respectively denotes an on-axis thickness of the third lens and the fourth lens. The camera optical lens in the present disclosure satisfies a design requirement of large aperture, long focal length and ultra-thinness while having good optical performance.
