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 negative 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: −5.00≤f1/f2≤−1.70; and 2.00≤R3/R4≤20.00. The camera optical lens can achieve a high optical imaging performance while obtaining a low TTL.
