Abstract
Provided is a camera optical lens including, from an object side to an image side: a first lens having a positive refractive power, a second lens having a negative refractive power, a third lens having a negative refractive power, a fourth lens having a positive refractive power, a fifth lens having a negative refractive power, a sixth lens having a positive refractive power, and a seventh lens having a negative refractive power, and the camera optical lens satisfies following conditions: 2.80≤v1/v2≤4.30; 5.00≤f4/f≤12.00; −4.00≤f5/f≤−1.50; and −20.00≤R13/R14≤−5.00. The camera optical lens has good optical performance while satisfying the requirements of ultra-thin, wide-angle lenses having large apertures.
