6. reasonable price
Kind of an understatement :>))
For the price of any one of the standalone 'premier' backs currently available
a buyer can get the AFD II kit and quite possibly every new AF lens Mamiya currently offers.
Probably have some change left over to pick up a couple of used manual lenses as well.
Assuming this product release (now slated for release 90 days away) is valid I think Mamiya has
made a very good tactical move.
The files might,conceivably,be slightly inferior to other products but the price point is sure
to attract a huge number of new 'devotees' to the MF digital world who probably could not have afforded to make this decision with other brands.
As most photographers are pretty brand loyal (even though we won't admit it) once they make a choice Mamiya has them in the fold for lenses,accessories and back upgrades for years to come.
