> Ultra wide-angle 8mm fisheye lens with exaggerated perspective and > approximately 180° angle of view, for dramatic effects > > Ultra-wide 139.3° diagonal field-of-view for 4/3 size image formats > Of course if you use the same lens with different sensor size, the result will be different. That's why the Nikkor 10.5 on a small sensor has a 180° diagonal while on a fullframe sensor the HFOV is around 180°.

At least now you should have a better idea whether or not you want that fisheye lens! I have a fullframe fisheye and it's quite practical to only take 6 pictures horizontally (I have a pano head so I also take a zenith, but I always have issues stitching the nadir, as the shot is handheld to avoid seeing the tripod). -- You received this message because you are subscribed to the Google Groups "Hugin and other free panoramic software" group.
