Yeah, shot noise does not matter.

Not much at base ISO, no.

Much more than EV=0.6 difference in DR.

For those interested in seeing what difference DR makes when shadows are pushed, a look at the comparison between the D800 (with excellent base-ISO DR) and the 5D3 (with so-so base-ISO DR) is instructive:

Nice spin. Now, show me how the m43 cameras compare.

#2: Warmer tones: all FFs are better.

I don't see any difference having to do with signal-noise performance here.

I do.

#3: FF better again, even the 6D in the blue color.

There is small difference in blue just as in case #1 above.

It is everywhere, not just in the blue color.

The m43 shot is not detailed enough.

The E-M1 shot is not approrpriate for judging resolution. There has been a lot of discussion on this forum about the fact that the DPR studio scene samples for several MFT cameras are marred by shutter shock (shutter-induced blur).

You can blame the diffraction for that but the noise is also blurred.

No the noise is not blurred.

It is. In the lower left here, there is a low frequency noise but not much high frequency. Compare with same square for the other cams - about the same (high-freq) noise but much less low frequency one. The other colors behave differently.

Go to ISO 100. The deep blue square has more blurred borders compared to the others. Look at the 6D crop - no such thing.
