Well, I rented a Hasselblad H2, with a 39 Meg back, the P45+ from PhaseOne. I have to admit I found it daunting and clumsy to use a bunch of gear that I don't know well, but that was to be expected. I was shooting industrial landscapes in bright daylight, trying to test out the dynamic range. Unfortunately there was a 5.4 earthquake here in LA, and then my wife's water broke, and we had a baby... so I never got to do my nighttime shots with it. Oh well. Baby and wife are quite fine, as are my other kids. The camera was returned unharmed. I am beginning to have the feeling that digital MF is a lot more than I need. I think I may end up buying a 1Ds, it just seems money well spent. More on this later.
