<p>Provided are a fisheye lens system and an image capturing device including the fisheye lens system. A zoom lens system includes a first lens system and a second lens system. The first lens group includes a first lens having negative refractive power, a second lens having negative refractive power, and a third lens having positive refractive power that are sequentially arranged in a direction from an object side to an image side. The first lens group has negative refractive power. The second lens group includes a fourth lens having positive refractive power, a fifth lens having positive refractive power, a sixth lens having negative refractive power, a seventh lens having positive refractive power, and an eighth lens having positive refractive power that are sequentially arranged in the direction from the object side to the image side. The second lens group has positive refractive power. Zooming is performed by varying a distance between the first and second lens groups.</p> |
