Where it's lacking somewhat is in full-well capacity. I'd guess the limit is actually the 12-bit converter. A 14-bit converter with the 12K electrons from ISO 160 and the same read noise as ISO 640 would give excellent DR at high ISO. Maybe for the GH3...

14bit is enough to count every single electron w/o noise in GH2 wells, minus at least 2 bits for noise... no need to 14 bits then in the output.
