Image circle for that lens, from what i can find, is 67.2 mm and designed for 24x36 sensor (43mm diag).
diagonal for that X2D sensor (32.9x43.8 X2D spec sheet) should be about 54.78 mm
So it seems to just cover the sensor with about 6mm +/- cumulative movement on the diagonal.
you could cut out a 67 mm circle from wax paper and move it over a drawn box of the sensor to see how much shift is possible.
Vignetting may be an additional issue.
Thanks for the clarification.
Just looking for a free lunch! LOL
Love the X2D, gets me back to the LUT I loved from Hassie prior H cameras I owned.
(went from H5D 60 to GFX, but just never as happy with the GFX for my work)
Hmmm, only "real" solution is put the X2D on the back of something like a Cambo with TS and a lens that gives me sensor coverage to mate to the X2D. More gear to buy and haul around - not fun at 78 years!
