Henry showing the difference between sensors

It is very clear that (me) stating that a 4x sensor difference yields a roughly 2x stop difference is a VERY BIG DEAL. Well, the A7 has 1.5x stop and the A7r has 1.8x difference (if I calculated correctly).

Could you show us where on the DxO graph between ISO100 and ISO6400 where the differences are 1.5 and 1.8 stops? Just answer with the specific ISOs please.

I see about 1/2 at almost every ISO, but not anywhere near the 1.5 you keep dreaming of.

Again, compare the ISO scores at http://www.dxomark.com/Cameras/Compare/Side-by-side/Sony-A7-versus-Sony-A7R-versus-Olympus-OM-D-E-M1___916_917_909
