PhaseOne digital back anyone?

After shooting the two Hasselblad digital cameras (see reviews on the Free Articles page), I’m left wondering how the equivalent PhaseOne backs perform. If any of you readers out there have compared the PhaseOne backs to the equivalent Hasselblad offering, please share your experiences by emailing me. I still hope to test-shoot a PhaseOne back, but I haven’t received a response from my local PhaseOne dealer yet. Also, I have a Mamiya ZD review coming, but I have to wait until the camera is released (NDA).

Update: My local dealer has impressed me with their knowledge, including a subject of great interest to me: infrared. It seems that a PhaseOne back can be supplied with clear glass over the sensor such that it can be used (with appropriate filtration on the lens) for infrared or color!
