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: 1.40≤f1/f2≤5.00; and 2.50≤R3/R4≤6.00. The camera optical lens can achieve a high imaging performance while obtaining a low TTL.
