Abstract
Disclosed is a camera optical lens, comprising, from an object side to an image side in sequence: a first lens having a negative refractive power; a second lens having a positive refractive power; a third lens having a positive refractive power; a fourth lens having a negative refractive power; a fifth lens having a positive refractive power; and a sixth lens having a negative refractive power; wherein, the camera optical lens satisfies: −4.50≤f1/f≤−2.20; 2.00≤f2/f≤5.50; −20.00≤(R3+R4)/(R3−R4)≤−2.50; and 3.00≤d9/d10≤10.00; where, f denotes a focus length of camera optical lens; f1 and f2 denote focus lengths of first and second lens respectively; d9 denotes an on-axis thickness of fifth lens; d10 denotes an on-axis distance from an image side surface of fifth lens to an object side surface of sixth lens; R3 and R4 denote central curvature radii of an object side surface and an object side surface of second lens respectively.
