Embodiment Construction
[0056] Please refer to the optical photography system of the first embodiment of the present invention Figure 1A , for the aberration curve of the first embodiment, please refer to Figure 1B , the optical photography system of the first embodiment includes sequentially from the object side to the image side:
[0057] A first lens 110 with negative refractive power is made of plastic, the object side surface 111 of the first lens 110 is convex, and the image side surface 112 is concave, and the object side surface 111 and image side surface 112 of the first lens 110 are are all aspheric;
[0058] A second lens 120 with positive refractive power is made of plastic. The object side surface 121 of the second lens 120 is convex, and the image side surface 122 is convex. In addition, the object side surface 121 and the image side surface 122 of the second lens 120 are all aspheric;
[0059] A third lens 130 with positive refractive power is made of plastic. The object side surfa...
