Hi Henning,

I think what you're saying is what I suspected. If I shift the back to the 
top, focus and tilt, then shift the back to the bottom, refocus (tilt 
probably won't be needed for the far objects), then I will have a different 
proportion of the image circle recorded on the sensor? Thats because 
refocusing changes the size of the image circle recorded, yes? And stitching 
will be difficult?

Thanks for clarifying...
Bob
