Actually, you can live view with all the H cameras even if you use an H1, 2, 4x, etc... with a Phase back. When hooked up to C1, go into live viewmode and just put the Hassy body in mirror up. I do this all the time. It's crude, but then again, all the P-backs with tethered live view were crude. I really love the Hasselblad system. I just never liked the H3D backs so I went with Phase for a sensor.
