Right, of course. I didn't think that through well enough. The
situation I was imagining would only pertain if you put a -
hypothetical - TS lens designed for a small sensor on a FF
camera. And then even without shifting. Thanks for the nudge.
But how do you explain the 1-2 stop darkening described by the
original poster/?

To Ken and the group,
The magnification factor continues to be confusing. The Canon TS
lenses are calculated to throw a an image circle large enough for a
FF sensor to be fully covered at maximum shift. Put a TS lens on a
camera with a smaller sensor, like the 20D, and the sensor will have
room to roam. The TS lens, or any lens for that matter, makes the
same sized image circle and magnification regardless of what camera
it is on - from 8mm cine to 8x10 sheet film.

Very interesting. I don't own a TS lens, but was wondering lately
how the image circle use would be with a smaller sensor. I've
often thought of getting the TS-E 90 for my 35mm to use as a
close-up lens: I wonder if what you're describing would change a
lot with longer focal lengths. The image circle gets smaller,
right? It seems possible that at some point it would become
possible to shift out of it.
