Abstract
A camera optical lens includes five-piece lenses, from an object side to an image side. The camera optical lens satisfies conditions of 0.65≤f1/f≤0.85, 1.20≤(R7+R8)/(R7−R8)≤1.75, −40.00≤f3/f≤−20.00, 0.50≤d5/d6≤0.80 and 1.00≤d8/d9≤1.30. Here f denotes a focal length of the camera optical lens, f1 denotes a focal length of the first lens, f3 denotes a focal length of the third lens, R7 denotes a curvature radius of an object-side surface of the fourth lens, R8 denotes a curvature radius of an image-side surface of the fourth lens, d5 denotes an on-axis thickness of the third lens, d6 denotes an on-axis distance from an image-side surface of the third lens to the object-side surface of the fourth lens. The camera optical lens of the present disclosure has excellent optical performances, and meanwhile can meet design requirements of a large aperture, a wide angle and ultra-thin.
