The angle of view is 180° vertical and horizontal (circular fisheye) when zoomed out to 8mm, and 180° diagonal (full-frame fisheye) when zoomed in close to 15mm. In DX format, 180° diagonal full-frame fisheye images can be obtained around the DX mark on the focal length scale. The latest optical design technology delivers high resolution even at the maximum aperture and superb reproduction capability of point light sources all the way to the periphery.
