Hi guys, I have the option to buy tomorrow the 1D X, serial number starting with 05.... I am not a professional, just a very enthusiastic amateur (I currently own the 5D II, plus 6 zoom and prime lenses). I have read about the err80 issue, and another one with the servo focusing over 10 fps. Do you think that both of these problems are firmware related, or hardware? I live in Greece, and it's probably impossible to have exchanged if is found faulty. Theoretically, I can wait to buy a bit later, but of course it's very difficult to wait... What would you advise? Warm thanks.
