I think it was already mentioned, but a shift lens on DSLR allows you to make very quickly panoramic or almost panoramic shots which are very easy to stitch together. You simply shift to one side, shoot, shift to other side, shoot, overlap the frames, or so I heard. No need for special pano head, no need for precisely found nodal point of lens. Even if some stitching is needed, it should be a much less hassle than stitching frames shot the other way.
Good light!
