It seems likely that the dual-gain implementation in the A7V will be part of the basic template for future Sony cameras. This will likely incline people to shoot more with mechanical shutter and may erode some of the appeal of the fully electronic shutter.
I do wonder how well the ES in the A7V will deal with the problem of banding under modern lighting.
Yes, this is very interesting for the future (and so I implore @chez & company to ignore this thread as it's obviously not the case for them). I think @snapsy already tested that DGO (mech shutter) results in *double* the number of bands.
The other question he & @ruthenium raised is why DGO does not work in ES on A7V (readout speed/tech or closing the shutter issue probably), while it does on MFT cameras. I also think Sony will overcome this limitation with the next Sony A1, and if we're lucky A9 too .
The question about fw upgrade is also an interesting one. I'd say that it does require some extra hw around the sensor, but on the other hand Nikon lacks DGO in Z6III while Panasonic has it in S1II, which use the same sensor...
