| 发明名称 | Wide angle lens system and electronic apparatus having the same | ||
| 摘要 | A wide angle lens system and an electronic apparatus including the same are provided. The wide angle lens system includes a first lens group having a negative refractive power, and a second lens group having a positive refractive power. The second lens group is spaced apart from the first lens group by a maximum air gap. The first lens group and the second lens group are sequentially arranged from an object side toward an image side. The second lens group includes a positive 2-1 lens group, a negative 2-2 lens group, and a positive 2-3 lens group, and focusing is performed by moving the 2-2 lens group along an optical axis. | ||
