The bad thing is that it is not a camera made from scratch
The good thing is also precisely that. It is the opposite of vaporware. A somewhat improved AFD, that is already being marketed by Phase One and Mamiya and is ready for market as we speak.
It is leaf lens ready, so glass is probably going to be made from scratch.
The no show of "European lens maker" is disappointing, unless I missed something...
I think that this is a conservative incremental move for a long term relationship Mamiya Phase One, (the trickle down for existing owners is may be, for example, Mamiya specific lens correction on the next Capture One 4 PRO program).
I hope that the two companies make good use of the momentum that this new camera brings.
By the way, can we truly call this "a new system" can we? probably, a new re branded improved model would be more accurate.
