Abstract
A camera optical lens includes five-piece lenses, from an object side to an image side, the five-piece lenses are: a first lens having a positive refractive power, a second lens having a negative refractive power, a third lens, a fourth lens having a negative refractive power and a fifth lens having a positive refractive power. The camera optical lens satisfies conditions of 0.60≤f1/f≤0.90, 1.80≤d6/d8≤3.20, 0.55≤f2/f4≤1.00, and 5.50≤f5/f≤10.00. Here f denotes a focal length of the camera optical lens, d6 denotes an on-axis distance from an image-side surface of the third lens to an object-side surface of the fourth lens, and d8 denotes an on-axis distance from an image-side surface of the fourth lens to an object-side surface of the fifth 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.
