True; i have sent the 4 CFV backs (which we use in the Art Academy) with the H'blad 503 bodies to , i think they do it in Denmark, for calibration/alligning. Costs: about 1600 euro for the 4 camera's. regards herman Given the apparently near zero tolerance of these flat plane sensors in relationship to their viewing/focusing systems; and their $7 - $50K price tags; one would expect that the final calibrated installation would be included in the price. I.E. I'm buying your back - here's my camera - line it up. To some extent this seems to be true with the Leica S2 and M9. I also wonder if this is the real price difference between the $7K Canon or Nikon Pro models and the ProSumer models.
