Abstract
Provided is a camera optical lens, which includes, from an object side to an image side, first to seventh lenses. The camera optical lens satisfies following conditions: 0.50≤f1/f≤0.80; 1.50≤f6/f7≤5.00; and 1.20≤d4/d5≤2.00, where f denotes a focal length of the camera optical lens, f1 denotes a focal length of the first lens, f6 denotes a focal length of the sixth lens, f7 denotes a focal length of the seventh 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 d5 denotes an on-axis thickness of the third lens. The camera optical lens according to the present disclosure can achieve high optical performance while satisfying design requirements for ultra-thin, long-focal-length lenses having large apertures.
