Abstract
A camera optical lens includes six-piece lenses, from an object side to an image side, the six-piece lenses are: a first lens having a positive refractive power, a second lens having a negative refractive power, a third lens having a negative refractive power, a fourth lens, a fifth lens having a positive refractive power and a sixth lens having a negative refractive power. The camera optical lens satisfies conditions of 0.35≤f1/f≤0.50, −30.00≤R4/R3≤−2.00, and 1.50≤(R5+R6)/(R5−R6)≤30.00. The camera optical lens of the present application has excellent optical performances, and meanwhile can meet design requirements of a long focal length and is ultra-thin.
