No they don't hit that tonality at the same time.
Yeah, they pretty much do. Compare shots with lifted shadow detail to shots exposed for the shadow detail. In terms of tone they both start to look like trash vs. the shadow exposed frame at about the same time. Geeks arguing in forums never notice this because they just shove the shadow slider all the way to the right and then cry about pattern noise.
Don't get me wrong. It's amazing what modern sensors and RAW processors can do. But past a certain point you are better off to expose and blend two frames. That point is not strictly determined by noise IMHO, and it's pretty close to the same for the sensors in question.
The Canon, at low ISO only, hits it a good 2 full stops sooner.
I don't see a 2 stop difference even ignoring tone and focusing only on noise. But I'm sure there's a ridiculous DxO graph some where that "proves" me wrong.
Funny that is meaningless and yet a 1/2 stop plus at the high-end is a radical advantage....
Who said that? Oh yeah...nobody.
let's be fair and honest about things, there is no need to insist that the cam you have has to be the single best at every last thing, if it is not at something, it is not.
And who said that? Oh right...nobody.
As I recall I painted the differences as minor and basically said it comes down to the photographer. Yet some how that triggered a defensive "Nikon be best!" rant.
