Abstract
A camera optical lens includes first to sixth lenses from object side to image side, with first, third and sixth lenses having negative refractive power and second and fourth lenses having positive refractive power, and satisfies: −3.00≤f1/f≤−1.50; 1.50≤d4/d6≤4.00; and R7/R8≤−8.00, where f and f1 denotes respectively focal lengths of the camera optical lens and the first lens, R7 denotes a curvature radius of an object side surface of the fourth lens, R8 denotes a curvature radius of an image side surface of the fourth lens, d4 denotes an on-axis distance from an image side surface of the second lens to an object side surface of the third lens, and d6 denotes an on-axis distance from an image side surface of the third lens to the object side surface of the fourth lens, thereby meeting requirements of a large aperture, a wide angle, and ultra-thinness while having good optical performance.
