I don't trust DXO. Not that whatever DXO said is untrue, but they are only looking at a single aspect of the camera. If you believe everything DXO tells you, then you shouldn't have jumpship. Also... I see heaps of professionals using Canon camera and achieve excellent results, I have seen heaps of professionals using other brands camera and achieve similarly excellent photos... that is why I say, they are the same.
But you can believe what you will, that is not for me to say or try to change your guts feeling. And I have always said and will maintain, sensor is not the only thing that made a good camera.
Finally, let me quote you a finding in DXOmark,
http://www.dxomark.com/Cameras/Comp...sus-Sony-A7R-versus-Nikon-D800E___919_917_814
Okay, let see,
Seemed like Nikon D5300 has a 13.9ev, while Sony A7R only had a 14.1ev... Sony having thus lesser than 0.5ev better than Nikon D5300... and as we all know, D5300 with kit lens is going off at pretty low prices nowadays, why the heck would anyone go to A7R if you just look at DXO? Secondly... the famed D800E is also only thrump the D5300 with 0.4ev... and so, people shouldn't spent that massively much on D800E, right?
