I'm new to the medium format photography world. I just bought the H1 and the Kodak ProBack 645h. I would like to get some opinions about what constitutes a good flash set-up for this combination. I mainly shoot studio portraits.
Take a look at the Profoto Acute 2 system. You can get them with Pocket Wizard receiver moduls built into the generators...which allows for totally sync cord free studio work. Some Sekonic flash meters can also be had with the same module so you won't be teathered to anything there either.
