If you pan the camera to take the sequence of photos to be stitched later, isnt the fact that the camera back is panning going to give you a curved "plane" of focus or in the case of vertical as well as horizontal panning, give you a spherical "plane" of focus?
I would think this could be masked with small apertures to gain depth of field, but what about geometry? I don't see how you could do architecture via stitching. Another thing, in order to get correct geometric projection, wouldn't you need to mount the camera such that the panning axis is at the nodal point of the lens instead of the usual tripod mount which is further back near the focal plane?
