Anyway, 1DX dynamic range results are in.

Who's results are in?  Anyone's but yours?

and big shocker.... he gets the same thing  ;)

(note that he did not normalize for ISO or MP so the 1DX and 5D2 look a bit better on that chart compared to the 5D3 than they do in reality, particularly note that the 5D3 DOES beat the 5D2 for high iso DR once you shift the 5D2 chart to account for it rating ISOs differently)

his charts shows that they did improve high ISO DR a lot in the 1DX though so it won't fall behind in DR there compared to D3s or D4, so yeah, ignoring a bit of color-blindness  ;), the 1DX should be all time low light king with probably about tied for best DR at high ISO (with D3s and D4) and best luminance SNR (perhaps by 1/3 stop maybe 1/2 stop over D4???) and with many more MP than D3s (making 'grain' look much better and allowing for more NR while maintaining the same detail).

So who's the winner? I'm interested in a camera for street portrait photography. What would be the best thing to use to get great skin tones in Canon lineup? Does the 1Ds Mk III remain the best thing for this?

The 1Ds3 is superior ISO 50-200.  Above 200 the 5D3 is better.

The 1Ds3 is superior ISO 50-200.  Above 200 the 5D3 is better.

So I went to DXO to check the difference between 5D III and 1Ds III (yes, I heard lot of negative stuff about this web-site) and here what I saw in the results for low ISO measurements:

Dynamic Range: 5D Mark III loses (~2% difference at ISO 100)
SNR: 5D Mark III wins (~3.6% difference at ISO 100)
Tonal Range: 5D Mark III wins (~0.3% difference at ISO 100)
Color Sensitivity: 5D Mark III loses (~0.4% difference at ISO 100)

Looking at those numbers I don't clearly understand why 1Ds Mark III is so superior. Does it handles uncontrolled light better? Or is it about self-convincing? (i.e. a camera that costs 8 grand makes better images as a matter of fact).

Or am I missing something?

Up to iso200
- total lack of noise
- DR
- strong colours
- no banding in the shadows

+8 million.  You are missing something badly.  You went off website specs instead of actually shooting with both and looking at your photos.  Brian is 100% correct on his assessment here.

Any chance to get this kind of comparison with 1Dx?  ;D

Check this out

From that test, I cannot see 1 stop over 5d3, at most half a stop, maybe still not as good as D3s or D4

It looks like a stop to me over 3200 ISO. Under that its very similar but thats amazing. The grain also looks better on the 1Dx.

I am confused about that.
Shouldn't the 1D X ISO 6400 look like the 1D X ISO 3200 IF compared to the 5D MKIII ISO 6400? Now that would be 1 stop. Or am I wrong?

The 5D3 @ 6400 ISO and the 1Dx @ 12,800 look simliar to me. I can see a good stop there when processing and  the final photo is done.

So who's the winner? I'm interested in a camera for street portrait photography. What would be the best thing to use to get great skin tones in Canon lineup? Does the 1Ds Mk III remain the best thing for this?

what ISOs would you be dealing with?
well lit, full sun street portraits or low light stuff?

the main thing would be the metamerism index (the real world difference this makes I'm not sure, it might be complex, nobody has looked into it carefully) and the banding, you can dig around the shadows more with the 1Ds3 since it doesn't have as much ugly pattern banding at low ISO
