Thanks for all the opinions and info thus far. Does no one want to jump in and speak about a Phase One camera/back situation? I used to shoot a P30+ on Contax.
I only have deep experience with two brands, Leaf and Phase. Love the look of the Leaf file (processed in photoshop) disliked the reliability of the back as it went in 4 times for major issues and/or replacement.
Leaf stood behind it, but it was a problematic day in day out tool for me, so I went with Phase.
My two phase backs have never had an issue and are even more viable today than they were when I bought them, as the software keeps improving, capture pilot for remote is great and the backs are solid, especially in tethering.
Since I use Contax and have a lot of backups, cameras aren't really my problem today.
Knowing this if I decided to buy another medium format camera I'd either go Hasselblad or Pentax.
Hasselblad's 40 mpx camera because it goes to 800 clean and phocus produces beautiful skin tones and because the price of the h4d 40 is pretty good. (Not great but good). The main reason I would go to Hasselblad is the lenses and bodies are in rental world wide and they make an autofocus and fast 100mm which is a real go to lens. Also Hasselblad has a mobile App and I hear that Phocus is finally stable.
The Phase/Mamiya DF I'm not in love with and doubt if I ever will be. The real issue of that body is the prism doesn't remove. That is a feature I use all the time on the Contax and when you need it, you really, really need it.
Now I'd amend all the above if the Pentax would tether and had a mobile app, because I believe the $10,000 price point is where these cameras should really be, (even though the Pentax also has a fixed prism).
BTW: I love the mobile apps to the I-pad. It makes the lcd on the camera irrelevant and finally stopped everyone from standing around the computer station.
