Hmmm, I guess, since the bayonette on the PB-4 rotates, one could
say that it does have rise/fall, swing, tilt, and shift (though only
on the front standard) - and they can be applied in any direction, since
it has what amounts to a rotating back as well. Sounds like pretty
complete view camera movements to me (though some are
relatively awkward to use...).
Hope This Helps
