Diego,
I am about to receive a Focomat 35, and have been "told" that each
lens is matched to the focusing cam. At one time Leica could match a
lens to the cam and allow accurate autofocus of other lenes. Seems
from what you are saying that this is not an option now. You can
disconnect the autofocus (I believe), and I would be surprised if the
Leica trained "independents" around the world were not capable of
matching a new cam combination for you.
Keep us informed as to your progress
Cheers
