Carlos,Bob, which Hassy back is that on your TC? Is that from a 3-Series system?
It is an H3D II 39.Sure this Alpa TC set up is very nice, what's the back behind ?
I was thinking about a 35mm lens with a Sinar54LV back.Tom,
It depends on the back and the focal length of the lens.
A wide angle non-retrofocus lens, which are commonly used on technical cameras, have very acute angles of incidence in the corners since the lens sits so close to the sensor. It is those acute angles that produce lens cast which is further exaggerated with a movement. The longer the lens, the less lens cast is produced.

And also on the design of the lens and whether it is retro-focal or not. I have a 28mm Rodenstock HR (retrofocal) that shows no cast whatever the shift is.Tom,

Is the main purpose for using one of these cameras with a digital back to more easily stitch together photos (using the horizontal/vertical shift movements of the camera), whether for a panorama or just to get a higher resolution image file? That appeals to me, since I've been doing more horizontal panoramas recently (mostly with my 35mm DSLR) and would like to make the most of my 16mp CFV-II back (by combining both horizontal and vertical shifts).
