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, 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 the following conditions: 0.90≤f1/f≤2.00; and 2.50≤d13/d14≤12.00, where f denotes a focal length of the camera optical lens, f1 denotes a focal length of the first lens, d13 denotes an on-axis thickness of the seventh lens, and d14 denotes an on-axis distance from an image side surface of the seventh lens to an object side surface of the eighth lens. The camera optical lens according to the present invention has better optical performance while satisfying design requirements for ultra-thin, wide-angle lenses having large apertures.
