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 having a negative refractive power, a third lens having a positive refractive power, a fourth lens having a positive refractive power, and a fifth lens having a negative refractive power, the camera optical lens satisfying conditions of 0.50≤R5/R6≤0.75, 0.80≤f1/f≤1.00, 0.80≤d3/d4≤1.15, 1.65≤d7/d8≤2.50 and 0.00≤R4. The camera optical lens can achieve excellent optical characteristics while meeting the designing requirement for having a large aperture and being wide-angle and ultra-thin.
