Re: a7S high ISO claim - - -over hyped or not ?

I appreciate the time you have taken to reply but we'll never agree on the DXOmark DR values. I trust my own image based testing much more.

While you have A7r, A7s one thing that would be very interesting...
In tungsten light how does ISO6400 on A7R compare with an A7s at ISO25600 with a 80A filter (should be similar shutter speeds).
It's something I experimented with nearly 10 yrs ago with the Minolta 7D.

The rational is well described here:

In other words can you use some of the advantage of the A7s after ISO6400 to get great colour and DR at high ISO and tungsten light.
