Camera optical lens

Abstract

The present disclosure provides a camera optical lens with six lenses including from an object side to an image side: a first lens having a negative refractive power; a second lens having a positive 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 following conditions: 3.00≤f2/f≤5.00; −10.00≤(R9+R10)/(R9−R10)≤−2.00; where f denotes a focal length of the camera optical lens, f2 denotes a focal length of the second lens, R9 denotes a central curvature radius of an object-side surface of the fifth lens, and R10 denotes a central curvature radius of an image-side surface of the fifth lens. The camera optical lens in the present disclosure satisfies a design requirement of wide angle and ultra-thinness while having good optical performance.
