Abstract
A camera optical lens is provided. The camera optical lens includes, from an object side to an image side, a first lens, a second lens having a negative refractive power, a third lens, a fourth lens, a fifth lens, a sixth lens, a seventh lens, an eighth lens, and a ninth lens. The camera optical lens satisfies following conditions: 2.00≤f1/f≤4.50; and 3.50≤d5/d6≤15.00, where f denotes a focal length of the camera optical lens, f1 denotes a focal length of the first lens, d5 denotes an on-axis thickness of the third lens, and d6 denotes an on-axis distance from an image side surface of the third lens to an object side surface of the fourth lens. The camera optical lens according to the present disclosure meets design requirements for large aperture, wide angle and ultra-thinness while achieving good optical performance.
