Abstract
Disclosed is a camera optical lens. The camera optical lens includes nine lenses in total, and the nine lenses from an object side to an image side are: a first lens with a negative refractive power, a second lens, a third lens with a positive refractive power, a fourth lens, a fifth lens with a negative refractive power, a sixth lens with a positive refractive power, a seventh lens with a negative refractive power, an eighth lens with a positive refractive power and an ninth lens with a negative refractive power. The camera optical lens satisfies: −1.80≤f1/f≤−0.60; 2.00≤d5/d6≤8.00; 3.50≤f6/f≤6.00. The camera optical lens has good optical performance, and meets the design requirements of a large aperture, wide-angle and ultra-thin.
