Using old X-Fujinon lenses on new Fuji X-mount?

This may help. The link below shows an X-Pro1 with an adapted M42 lens (EBC Fujinon 50mm f1.4).

Also check out http://en.wikipedia.org/wiki/Flange_focal_distance, where it says the FFD for Fujinon FX lenses is reported to be 43.50 mm, that's identical to Minolta MD lenses. So you can try an M42 to XP1 adaptor or Minolta MD to XP1 adaptor to see if your lenses fit.
