"Right now it feels like things are turning upside down and I will end up being a Nikon user! Canon must respond with the 4K EOS or even a 5D X if they are to not completely fall behind the competition."They also compare the new Nikon very favorably to the Panasonic GH2, which, when hacked, is still world-class in its performance/price ratio. Panasonic should be very happy with its GH2, since it is the only thing keeping me in the Micro 4/3 fold. The E-M5 may prove exciting, but not until I see a test that controls for ISO variation vis-a-vis noise performance.
As it stands, I have never been more tempted to really lay down the cash and buy Full Format like I am with the D800. I'm definitely waiting, though, because I want to see what Sony has.
