Abstract
A camera optical lens, includes a first lens power, a second lens, a third lens, a fourth lens, and a fifth lens. A focal length of the camera optical lens is f, a focal length of the first lens is f1, a focal length of the third lens is f3, a focal length of the fourth lens is f4, a refractive power of the fourth lens is n4, an axial distance from an image side of the fourth lens to an object side of the fifth lens is d8, an effective half caliber of an image side of the fourth lens is SD8, the maximum image height of the camera optical lens is ImgH, an optical total length of the camera optical lens is TTL. The camera optical lens satisfies conditions: 0.5<f1/f<1; 1.55<n4<1.7; −3<f3/f4<−0.5; 0.2<SD8/ImgH<0.5; and 0.07<d8/TTL<0.3.
