Abstract
The present disclosure relates to the field of optical lenses and provides a camera optical lens. The camera optical lens includes, from an object side to an image side: a first lens; a second lens having a positive refractive power; a third lens having a positive refractive power; a fourth lens; a fifth lens; and a sixth lens. The camera optical lens satisfies following conditions: 3.00≤f1/f2≤6.00; and −7.00≤(R1+R2)/(R1−R2)≤−1.00. The camera optical lens can achieve a high imaging performance while obtaining a low TTL.
