     Here, the focal length of the whole camera optical lens  10  is defined as f, the focal length of the first lens is defined as f1. The camera optical lens  10  further satisfies the following condition: 1 f1/f≤1.5, which fixes the positive refractive power of the first lens L 1 . If the lower limit of the set value is exceeded, although it benefits the ultra-thin development of lenses, the positive refractive power of the first lens L 1  will be too strong, problem like aberration is difficult to be corrected, and it is also unfavorable for wide-angle development of lens. On the contrary, if the upper limit of the set value is exceeded, the positive refractive power of the first lens L 1  becomes too weak, it is then difficult to develop ultra-thin lenses. In one example, the following condition shall be satisfied, 1.08≤f1/f≤1.46.

A ratio within this range can effectively reduce the sensitivity of lens group used in camera and further enhance the imaging quality. In one example, the following condition shall be satisfied, −1.85 f3/f4 0.55.
