Abstract
The present disclosure a camera optical lens comprising, from an object side to an image side, a first lens having a positive refractive power, a second lens, a third lens having a positive refractive power, a fourth lens, and a fifth lens having a negative refractive power, the camera optical lens satisfying conditions of 0.45≤f3/f≤1.00, 2.50≤d4/d3≤4.50, 1.50≤d7/d8≤3.00 and 2.00≤(R3+R4)/(R3−R4). The camera optical lens can achieve excellent optical characteristics while meeting the designing requirement for having a large aperture and a long focal length and being ultra-thin.

A camera optical lens comprising, from an object side to an image side:
- a first lens having a positive refractive power;
- a second lens;
- a third lens having a positive refractive power;
- a fourth lens;
- and
- a fifth lens having a negative refractive power;
- wherein the camera optical lens satisfies following conditions:
