Right, I'm willing to accept that increasing the iso setting on the g3 from 800 to 1600 will reduce noise.What I wondered about was this exchange:

I'm following your example, so far.

On the other hand, if one set both at 3200 maintaining the same exposure they would no longer be directly comparable, but the G3 would appear noisier to a naive observer.
