Abstract
A camera optical lens includes, from an object side to an image side, a first lens having positive refractive power, a second lens having negative refractive power, a third lens having positive refractive power, a fourth lens having negative refractive power, a fifth lens having refractive power, a sixth lens having positive refractive power, and a seventh lens having negative refractive power. The camera optical lens satisfies: 2.90≤v1/v2≤4.50; 4.00≤f3/f≤10.00; 1.50≤d1/d2≤4.00; and 3.00≤R7/R8. The camera optical lens has good optical performance while meeting the design requirements of a large aperture, a wide angle, and ultra-thinness.
