This is false.

The 30% is 2/3 stops so instead of shooting at ISO3200 you are shooting at ISO4200. In bright sunlight it doesn't matter too much if you use ISO100 or ISO160.

The first version was quoted to divert 30% of the light to the AF sensors. That is 0.51EV on the log2 scale, to be exact, not 2/3 of a stop.

The NEX 7 and A77 show slightly less than half a stop difference (second generation SLT design, no more ghosting either).
