Abstract
A camera optical lens is provided, including from an object side to an image side: a first lens; a second lens having 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, wherein the camera optical lens satisfies the following conditions: 2.00≤f1/f≤5.50; and 1.50≤d15/d16≤9.00, where f denotes a focal length of the camera optical lens; f1 denotes a focal length of the first lens; d15 denotes an on-axis thickness of the eighth lens; and d16 denotes an on-axis distance from an image side surface of the eighth lens to an object side surface of the ninth lens. The above camera optical lens can meet design requirements for large aperture, wide-angle and ultra-thinness, while maintaining good imaging quality.
