Sorry, I must be going dyslexic. I forgot to type "look" But yes, I mean that the iso 12800 results from the A7S look like the results I get with iso 6400 with the A7 in low light.
I would really love seeing a direct comparison between A7S photos vs downsized A7 photos. It´s the difference between me spending us$1200 or us$2500 on second camera for the A7 I already own!
Here are some samples from my A7 and a Canon FD 50mm 1.4. I had high hopes to have much cleaner iso 6400 with the A7S in similar conditions...and much better iso 12800 (which for me is useless for professional work with the A7).

Noise from the A7S using ISO 12,800 @ 12 meg is like A7 using ISO 6400 @ 24 meg … is that what you mean? One stop difference sounds like a wash when comparing similar print sizes.
If that is true, then why would one want to be stuck with 12 meg at ISO 100 to 400 for a majority of images one would normally shoot where noise isn't an issue?
I think you are right, it is very hard to evaluate images and ISO performance without access to the RAW files. It would be interesting if someone had both the A7S and A7 (or A7R) and could shoot a low light image at the same distance using the same lens (especially with people in the frame), then compare the full image on A3 prints for noise and color.
