i've just bought one... perfect at 50 iso, nearly as perfect at 100 iso, not so bad at 200 iso (it depends on light), not really good at 400 iso.
i quite like how it renders colors... much more natural or even film like than a P45+ ...
the new GUI is nice.
it needs several battery for a complete day of shooting.
is your shop selling the complete kit ? DM33 + DF + 80 Af or Afd or phase one or SK ?
