Hi Don,
In order to avoid changes in perspective, the axis of rotation has
to be about the front nodal point of the lens. The front nodal point
is usually somewhere inside the lens, and not near the film plane.
Panoramas constructed with multiple still shots are usually done
in vertical portrait format, so you will need a way to mount
the camera on its side. The rotation almost NEVER goes through
the camera body tripod mount, whether centred or decentred, like
on the BP-300.
For an indepth explanation, see: http://www.panoguide.com
The author, James Rigg, now uses a digital camera (as do I), but
has produced panoramas using various EOS gear, including an
EOS 1000FN and an EOS 50E. E.g. see:

Rotating about the lens nodal point is also one of the techniques
used for "forced perspective" motion pictures. I am reminded
by Chris Daida's upcoming nuptials and the "Canon glass vs wife"
thread of the B-grade horror movie: "Attack of the 50 foot woman"
