ISO3200 without any NR looks better than my 5dii WITH NR
ISO5000 looked really good quality too, especially with some NR.
The files seemed to hold up really well to developing (the colours are still accurate and the sharpness is great!) - and the focussing must have been working hard to get those indoor shots in focus!
ISO6400 seemed similar to ISO3200 on my 5dii, which is what I was expecting..
Very impressed. IQ looks like it's a real step up from my 5dii.
