I have to disagree with both of you on this point. The 645D and 645Z would have had virtually no market as a camera body on its own. It takes lenses to complement the body to create a camera “system.” Without screw-drive focusing (and thus compatibility with two handfuls of prime and zoom FA-series lenses), a buyer would have had only 1 or 2 available lenses, and those at a cost that would have doubled the cost of the 645 digital camera system. Yeah sure, there are at least as many 645 A-series lenses out there, but lenses that are manual-focus only are so last century! And only for the young with good vision. And those aforementioned youngsters with good vision are less likely to have the financial capacity for a digital 645 camera system. Without backward compatibility the Pentax 645 digital bodies would not have happened.
