Had the scare of my lifetime just now.
Was going through some photos I took today and saw two with black bars at the 'top edge' of the frame. Both of these were when shifted one way.
I was playing around with the tilt and I think I went almost full tilt in those two shots. Both were one exposure of three (left, center, right) and (top, center, bottom) in the other. Both only showed it at the same shift exposures.
After gathering my breath together, I realize at full shift + full tilt, it is easily possible to have this happen.
Right? RIGHT? Somebody please confirm that for me so I can (finally) go to bed
Here's one of the shots, click for slightly larger
f/22, 8 seconds, the distance was probably a few feet.

Can someone try this with their lens?
1. Align both tilt and shift "axes" to coincide. As in you should be able to tilt and shift from side to side or top to bottom.
2. Shift to one extreme, let's say left.
3. Tilt to the other extreme end, the right, in this case.
4. Make sure the exposure is correct for the shot, on live view or otherwise.
5. Fire up the liveview and move the focus ring from one end to the other.
Do you see a black edge? I'm guessing that's the image circle's boundary.
