GH3 noise at base ISO very good.

And I don't believe them. I see the same similarity to my EPL5. what makes a paansonic sensor a Panasonic one? May be like Nikon changes some things in the Sony sensor they get to get their prefered output I think. We'll see....it is not important. otoh: would be best if it is a completely Panasonic designed and fabricated sensor so we are not depending on one manufacturer to do everything right....
