For me to upgrade to a 1D3 what minimum level of improvements would

A. ISO useable at 6400, equivalent to todays ISO 800 would do it.

This one is basically impossible as it would require quantum
efficiencies greater than 100%.

That's what you'all said about Canon getting to an almost
"noiseless" ISO-1600

When did I say that? I wouldn't have said that because "almost noiseless" is a meaningless term.

All I'm saying is that they can't get ISO 6400 to look like ISO 800 does now with the same size sensor. That's 3 stops. If QE is 20% now, that would mean it would have to be 20% * 8 = 160%.

BTW, they may be able to get 1-2 stops, ultimately. Not 3.
