And this assumes that you want a perfect join, from top to bottom.
Surely, with all the other problems that exist in lenses, you would not
want to use the whole coverage of the lens, top to bottom, when joining
images to make a biggy?
So, why bother with a shift lens, unless the fiddling with the shift is
an end in itself? ;-)
