After shooting with this camera for some months now I can add, that there are some noise at base iso (200) when you print out huge, as I do sometimes.
I am still happy shooting with this camera, and for some pictures it is OK - or even fine - with some grain, but for some landscapes printet out huge this noise degrade some details= Not much, but it is there if you go for very detailed landscapes in A3+ or larger.
This is not the case with e.g. my former Nikon D700 (also base iso 200) and not with my D3x or D700
You will also see some degradation if you do huge PP.
But I will still say it is a VERY fine camera,this mentioned here is just if you talk very detailed.
