the main point is that a 300$ pro software that won't support a top pro DSLR for some stupid marketing reason...its a real shame!
Maybe Pentax should step up and make a raw conversion software.
Phase One has always kept the Pentax 645D and Lecia files in a non supported fashion. Their support for 35mm DSLR files is hit and miss. For example, they made one attempt to make a profile for the D800e and it was less than perfect, and as far as I know never updated. I often use the Phase One IQ250 profile on my D800e files however C1 will open these so it's much easier to work with them. The profile for the D810 is much better in C1 ver 8. Their profiles and raw support for Fuji is excellent.
I believe it's possible to convert the 645z to a file format so that Phase One will open it as a IQ250 file as there has been a lot written about this. So it can be done.
If the 645z takes off to mainstream, their might be a utility, 3rd party, that will make the conversion so you can work with the files in C1.
The other big loss to users is the tethering support for the 645z/d and Lecia DSLR. C1 has an excellent tethering ability. I have used it with Canon, Nikon and Phase backs.
I don't believe you will ever see Phase One, openly, support the 645z. It's not just the 645z, as they don't support any other Medium format back I am aware of, besides Phase One.
For now there is always ACR and LR and LR 6 should be out soon.
Dare I say it, one of the reasons I went with a P45+ back in 2008, was that I had been using C1 since 3.7.6 and loved it on my Canon files. I knew that I would be paying a lot for the back, loved the Phase One software already so it did steer me to purchase a Phase One back. Since moving to a tech camera, I am even more dependent on C1.
