Patent attributes
A camera optical lens includes five-piece lenses, from an object side to an image side. The camera optical lens satisfies conditions of −3.50≤f2/f1≤−1.80, 1.00≤(R7+R8)/(R7−R8)≤1.75, 1.30≤d6/d4≤2.00, 5.00≤(R5+R6)/(R5−R6)≤20.00 and −5.00≤R9/R10≤−1.50. Here f1, f2 denote a focal length of the first lens and the second lens; R5, R6 denote a curvature radius of an object-side surface and an image-side surface of the third lens; R7, R8 denote a curvature radius of an object-side surface and an image-side of the fourth lens; R9, R10 denote a curvature radius of an object-side surface and an image-side surface of the fifth lens; d4 denotes an on-axis distance from an image-side surface of the second lens to the object-side surface of the third 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.
