Abstract
The present disclosure relates to the field of optical lenses and provides a camera optical lens sequentially including, from an object side to an image side, first to seventh lenses. The camera optical lens satisfies following conditions: 1.80≤f4/f≤5.00; −1.50≤f6/f7≤−1.00; and 1.20≤d8/d9≤1.60, where f denotes a focal length of the camera optical lens; f4, f6 and f7 denote focal lengths of the fourth, sixth and seventh lenses, respectively; d8 denotes an on-axis distance from an image side surface of the fourth lens to an object side surface of the fifth lens; and d9 denotes an on-axis thickness of the fifth lens. The camera optical lens according to the present disclosure can achieve high optical performance while satisfying design requirements for ultra-thin, wide-angle lenses having large apertures.
