[0114] Please refer to the first embodiment of the present invention figure 1 , please refer to the aberration curve of the first embodiment figure 2 . The image-taking optical lens group of the first embodiment is mainly composed of four lenses, which in sequence from the object side to the image side include:
[0115] A first lens 110 with a positive refractive power, the object side surface 111 and the image side surface 112 are convex surfaces, the material is plastic, the object side surface 111 and the image side surface 112 of the first lens 110 are both aspherical;
[0116] A second lens 120 with negative refractive power, the object-side surface 121 is concave and the image-side surface 122 is convex, the material is plastic, the object-side surface 121 and the image-side surface 122 of the second lens 120 are both aspherical ;
[0117] A third lens 130 with negative refractive power, the object side surface 131 is concave and the image side surface 132 is convex,...
