[0080] Please refer to the first embodiment of the present invention Figure 1A , for the aberration curve of the first embodiment, please refer to Figure 1B . The image-taking optical lens group of the first embodiment is mainly composed of four lenses, which include sequentially from the object side to the image side:
[0081] A first lens 110 with positive refractive power, its object-side surface 111 and image-side surface 112 are both convex, and its material is plastic;
[0082] A second lens 120 with negative refractive power, the object-side surface 121 is concave and the image-side surface 122 is convex, and its material is plastic;
[0083] A third lens 130 with positive refractive power, its object-side surface 131 is concave and image-side surface 132 is convex, its material is plastic, and the object-side surface 131 and image-side surface 132 of the third lens 130 are non- spherical; and
[0084] A fourth lens 140 with negative refractive power, its object-si...
