I'm going to add to this thread, as things have progressed somewhat since I last posted and I am eager for further info from people so I can continue shooting with my RZ set up.
I managed to get another adaptor, so I could also use my RZ with Phase/Mamiya fit backs-I got the HX705 rather than the one for the D series RZ67
I found that setting an IQ280 at zero latency and using the wake up synch cable, it worked great
But ...I can't fire it from the computer!
I do a lot of large set overhead photography and it makes my life a lot easier to fire from the computer.
So ,what I would like to know is ,is there a cable available to do this with a phase one back, or perhaps Leaf have a back I could achieve this with?
Ideally the back would also have USB3 on it rather than just firewire and be 60mp plus
I suppose other work arounds would be a really long cable release ,or maybe something could be achieved with wireless transmitters.
Any info appreciated
