  • Drum fisheye photo If you attach DSLR with Focal length multiplier>1 to Sigma 8mm f4 EX fisheye lens, the two margins in the final fisheye images will be cut. We call it drum fisheye image derived from its shape. 6 images in total, including the zenith and the nadir, would be enough when stitching panorama in our panorama stitching software.
