[mathematical expression 4]
Wherein, f1 is the focal length [mm] of the first lens, and f4 is the focal length [mm] of the 4th lens.
Mathematical expression 4 can be the qualifications for limiting the refracting power of the 4th lens.That is, if the value of f4/f1 is number
More than the upper limit value of formula 4, then camera lens may be caused due to the refracting power enhancing shared by the 4th lens 40 in camera lens module
The resolution ratio of module 100 reduces, or makes the total length of camera lens module 100（That is, the length of whole optical system）It is elongated.
[mathematical expression 5]
Wherein, f is the focal length [mm] of whole camera lens module, and f4 is the focal length [mm] of the 4th lens.
