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.
