Ok thanks to all for the responses, I have another question, I have the posibility to buy a Imacon Ixpress digital back, the thing is that the back is mounted for a Mamiya 645 AFD, but I do not have that camera, I have the Hasselblad and a Mamiya RZ ProII.
Did you know if there is any way to change the adapter to use in Hasseblad or RZ 67?
Thanks
Best
