Abstract
A camera optical lens includes, object side to image side, a first lens having positive refractive power, a second lens having positive refractive power, a third lens having negative refractive power, a fourth lens having positive refractive power, and a fifth lens having negative refractive power, and satisfies: 1.10≤f1/f≤1.50; 0.40≤R3/R4≤1.00; and 1.00≤d5/d6≤2.00, where f is a focal length of the camera optical lens, f1 is a focal length of the first lens, R3 is a central curvature radius of an object side surface of the second lens, R4 is a central curvature radius of an image side surface of the second lens, d5 is an on-axis thickness of the third lens, and d6 is an on-axis distance from an image side surface of the third lens to an object side surface of the fourth lens, thereby having a large aperture, a wide angle and ultra-thinness with good optical performance.
