Abstract
The present disclosure relates to a camera optical lens satisfying following conditions: 3.00≤f2/f≤5.00, 13.00≤d5/d6≤25.00, 3.00≤(R5+R6)/(R5−R6)≤10.00, and 5.00≤R3/R4≤50.00; where f denotes an overall focal length of the camera optical lens, f2 denotes a focal length of a second lens, d5 denotes an on-axis thickness of a third lens, d6 denotes an on-axis distance from an image-side surface of the third lens to an object-side surface of a fourth lens, R5 and R6 respectively denote a curvature radius of an object-side surface and the image-side surface of the third lens, and R3 and R4 respectively denote a curvature radius of an object-side surface and an image-side surface of the second lens. The camera optical lens in the present disclosure satisfies a design requirement of large aperture and wide angle while having good optical functions.
