A compact camera lens is provided to achieve high resolution above mega pixel by mixing spheric lenses and aspheric lenses. A first lens(L1) has a positive refractive index and comprises a convex plane toward an object. A second lens(L2) is located next to the first lens, and has a negative refractive index. A third lens(L3) is located next to the second lens, and has a positive refractive index and a convex plane toward an image. A fourth lens(L4) is located next to the third lens, and has a positive or negative refractive index. |
