As a Phase owner, I share people's concern with not having a modern, in-production camera system compatible with Phase (other than Mamiya).
To that end I spoke with Phase this week, and they told me the following (shared with their permission):
1) Phase backs will be usable with the Hy6. No timeframe specified, and when questioned on whether this would be a simple mechanical adaptation with a cable, or a true full (electronic) integration, they could not specify at this point in time.
2) Phase will be announcing a new camera platform later this year. No details on the camera platform, and the timeframe provided was Q1 '08. "...we will... have our own (open ended) camera platform in Q1 08."
Dealers are supposed to have some information on this as well.
So I hope that comes as a relief to some Phase owners (it did for me), that Phase appears to have some interesting developments in store in the near future.
Best regards,
Brad
