Re: I think he's right on that encoding, but tonal range suffers.

and the smart thing would be to optimize per RAW file how the bits are weighted- which is what JPEG does in the block sections (hence can do better than the "8-bit" would suggest).

That said, I am not seeing how the EM5 would do 12.5 stops at ISO 1600. To me the Tech Radar results are obviously wrong.

Interesting point. If it is a non-linear encoding, would Dx0 measure any degradation in tonal range?

I don't think that the E-M5 stores it's raw files any differently than any other Olympus camera because UFRaw is able to decode the E-M5 raw files and it doesn't have explicit support for it.
