For example, if a 180 degree fisheye lens made a 360 degree sweep, the aspect ratio would be 1:2. If a 180 degree anamorphic lens were used, then it might be possible to have a 1:1 ratio that certainly would be panoramic. (don't ask me where to find a anamorphic fisheye lens)

On the other hand, you could use a telephoto lens and make a 1:20 image that would not be panoramic at all.
So what would you suggest as a definition of a panoramic image? One that spans at least 120 degrees horizontally? Should we not consider aspect ratio at all for the definition of a panoramic image?
