Crops D3 x D4 (Marius/Horshack) and D3 x D3s (IR)

I used the jpegs Horshack produced from Marius Godeanu's NEFs at 6400/12800 from D3 and D4 with ACR (see http://forums.dpreview.com/forums/read.asp?forum=1021&message=40355741 and http://forums.dpreview.com/forums/read.asp?forum=1021&message=40362850 ), cropped at 100% side-by-side, then used 6400 and 12800 NEFs of D3 and D3s from Imaging Resource and used same ACR settings (ChrNR=0 and Neutral profile) to generate a (not so similar) reference comparison.

1- D3xD4



2- D3xD3s

Good shooting and good luck

They look like the same SCENE... how can that be? I am confused...

However, right side looks tighter, cleaner...

Either the D4 is not 100% crop, or they're shot with different focal lengths, right? Assuming same/no NR on both?

Same focal length. The D4 image was downsampled to match the D3's resolution.

They are the same scene, but D4's have been downres'd to match D3's.

Hope you don't mind ... Many people, including myself, are lazy to go and download full res images and then compare them. And I wanted to have the D3xD3s comparison images together. I think the D4 looks a bit cleaner than the D3s' from these crops, what do you think? But not more than 1/3 stop, so actually they should look same at full res.

And I can't see more chorma noise as Marianne has mentioned and some saw on first samples. Likely that was in-camera settings' effect.
