US 2022/0091385 A1 · CAMERA OPTICAL LENS

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, a second lens, a third lens, a fourth lens and a fifth lens. The camera optical lens satisfies conditions of −8.00≤f1/f5≤−3.00, R3/R4≤−2.00, and 3.00≤(R7+R8)/(R7-R8)≤15.00. Here f1 denotes a focal length of the first lens, f5 denotes a focal length of the fifth lens, R3 denotes a curvature radius of an object-side surface of the second lens, R4 denotes a curvature radius of an image-side surface of the second lens, R7 denotes a curvature radius of an object-side surface of the fourth lens, and R8 denotes a curvature radius of an image-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.
