Abstract
The present invention discloses a camera optical lens with six-piece lenses including, 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. The camera optical lens satisfies the following conditions: 0.60≤d9/f≤0.80, −30.00≤R9/R11≤−10.00, and −5.00≤f1/f≤−2.00. The camera optical lens according to the present invention has excellent optical characteristics, such as large aperture, wide angle, and ultra-thin.
