That is also incorrect. If we set ISO 6400 on both cameras, the exposures will be roughly equal on both cameras, again, aotbe.

The E-M5 will, in both cases, simply 'underexpose' by almost a full stop from what its sensor would allow, then it will 'brighten' the result (if you're shooting JPEG) or tell your raw editor (some, not all raw editors) how much to 'brighten' the RAW file, per default, when you open it, to make up for the difference.

OK. So supposing that the dynamic range is the same for both cameras/sensors I will expect noise increasing while 'brightening' in the resulting image. And it answer why DXOmark's high-ISO metric is about the same for G6 and E-M5 (639 vs 826, ~25%, not a full stop). Am I right?
