the IQ is a lot better then the 7D and I compared it to the 1dmkiv and it holds its own against that camera.

I've seen nothing so far to suggest that the this new 7DII can hold a candle to the 1D4 as far as image quality goes in the most important ISO range of around ISO 200-800. Those examples are just in camera produced jpgs at an ISO I will certainly never even try. Let's see the RAW files side by side with similar sharpening and NR applied before jumping to any wild conclusions.


ETA : I took a look at the jpg's for the ISO 400 examples (the most important ISO to me) and they look pretty awful to me. There are a lot of clumps in the shadows behind the wine bottles and the colors bleed into the backgrounds from the NR.

OK, I downloaded the ISO3200 Raw file from imaging resource, then used Faststone viewer to open the file and it allowed me to save a full res tiff file which I opened in PS and saved a 100% crop of the ISO3200 image here is the file:

Don't know what exactly the program is doing but as far as I can tell it is converting the File, it certainly does not look like the jpeg version of the file posted on the site and shows all the noise, so I don't think it is using the embedded jpeg.  Comments from the experts??

Assume people can do the same for RAW files at the ISO that interests them.

That crop looks nothing like the JPG on their site. For a start it has noise, of course, but also detail. A quick slide of the colour noise slider would sort out much of the problems there. But the red colour noise is very much similar to the old 7D.

Yes Chris' sample is easily worked out in LR, even as a jpeg. I've tried, really encouraging for an iso3200 shot.

A guy on dpreview made 7D/7D2 RAW comparions : http://www.dpreview.com/forums/post/54413318.
Looks like the 7D2 is about 1 stop better there.

It certainly does look pretty raunchy as presented. I suspect we'll see maybe a stop improvement over the old 7D. That might be enough too as having ISO400 pretty clean would be nice.

Well currently the Nikon D7100 is rated at 1256 ISO and the 7D at 856 by DXO. A one stop improvement on this scale would have the 7DII at 1712. On that scale a one stop improvement leap frogging the D7100 seems unlikely.
