Ok, if you crank up the NR that high then you can make a Pentax Q look as good as a 645Z. Honestly, these results you've shown are pretty meaningless as you've scrubbed all detail out of the image. DxO Prime is an excellent tool, I use it for all of my indoor sports work, but it requires a deft touch. I can see the argument that m43 punches slightly above it's weight but claiming only 1 stop difference is complete nonsense.

As I mentioned previously the settings are all defaults so I did not crank up either NR or sharpening or any other setting. You are in denial.

Wait wait wait, this is quite amazing.

I present two images showing that ISO 3200 on the EM1 looks essentially identical to ISO 12800 on the 5D3. You respond by posting two shots with such incredibly heavy noise reduction that there is zero detail left, and yes DxO Prime's defaults are very heavy handed, as evidence that there's only a stop of difference in high ISO performance between m43 and FF.

Actually DxO's NR retains details better than any other raw converter and it is not heavy handed at all. You can try Capture One with the same result. The details in the images are quite consistent with the ISO level. You are more driven by a preconceived notion of what should be rather than the actual result.

You think I'm the one in denial? I honestly am unsure if you're pulling my leg here or not.

I actually own both cameras. I know how they behave. DxO Prime certainly does retain detail better than other noise reduction algorithms, but you've severely overdone it in your example.

Apparently you have not been reading what I wrote earlier. I have not overdone anything. Why don't you download and process the 5D3 ISO12800 image and post a better result?

To get good results from DXO Prime you have to have a light touch with the settings. I know, I used it all the time for indoor sports work. There's zero detail left in the examples you showed. Of course they'll look similar! All you've shown is that apparently you like waxy images with no detail.

I would absolutely thrilled if the E-M1 was within 1 stop of the 5D3 as it would allow me to leave my FF kit at home in a wider range of situations, but unfortunately that's just not the case. I see you've also just completely ignored the example I showed earlier that shows the actual difference between the two sensors. In your example you may just as well have used a 10 pixel wide gaussian filter.
