I didn't really doubt that you knew, Chris, but couldn't resist the chance
to vent!
Necessary use of a tripod would apply to a real shift lens too, so nothing
lost there.

Thanks, Piers.
I had worked out that it was shift alone; I suppose tilt is
self-explanatory.
But what I find hard to appreciate is that such small movements in the lens
can give you such a change in apparent level of camera; it's much more
effective than merely raising the camera with your arms, for instance.
The other snag is that, with this system, you need really to have the camera
on a tripod.
