3D-Kraft posted that Sony A7rIi vs A7s High ISO comparison (video on top):
The image from the A7RII shows some more detail due to its downscaling from a 15 MP sensor readout. At 25600 ISO there is a slight advantage for the A7S. Regarding noise, the A7RII is not far behind the A7S but the A7S is able to keep up more details at very high ISO.
Diglloyd posted an article about the Shutter Vibration with the Electronic First Curtain Shutter on the A7rII:
The lack of shutter vibration possible with an EFC shutter means that any ultra high performance but physicall awkward or large lens like Zeiss Otus or even long teles like the Leica 280mm f/4 APO-Telyt-R can be shot with superb results and no fear of damage to sharpness by shutter vibration. (and Again on a second article): This is serious value from the IBIS technology and two compelling reasons that some shooters are best off abandoning the DSLR.
High ISO A7rII comparison at Newshooter:
From the outset, it is clear that the full frame mode on the a7RII isn’t as good as the a7S. The image is quite noisy and doesn’t compare well to the a7S. At all ISOs from 3200 onwards the a7S bests it and I would not use the a7R II this way.
