Why complain about DR any longer? Jeez, it like when people asked me why shoot slide film? It doesn't have enough DR is what they'd complain about but I loved my velvia 50.
This debate was not about complaining about DR. Trumpet was making some rather bold claims, and dismissing the original point Art_d was trying to make. The debate has been about the validity of Trumpet's claims, as in many cases they are wildly off base. I'm a Canon fan, I love my gear and I wouldn't give up my glass for the world. I think there is more to IQ than DR (hell, I've argued that side of the fence far more than I've argued the other side), and for what I shoot most of the time, wildlife and birds, low ISO DR is a moot point anyway, and Canon has the high ISO, accurate AF, high frame rate end of things covered more than good enough.
That said, you cannot simply offhandedly dismiss the value of more DR at low ISO for certain types of photography as Trumpet has been trying to. They may be limited in number, but they certainly are not limited in scope. And we aren't talking about something on the order of a third of a stop, which would be largely irrelevant.
There is obviously a serious misunderstanding when one thinks that the difference between the 5D III and the D800 in terms of ratio, by convoluting the argument into a comparison of cars....one that goes 95mph and another that goes 105mph...as an example of the difference in DR between those two cameras. The fact that every "stop" is a doubling seems to have been lost. Two stops is a FOUR FOLD increase in dynamic range, and that is more like the difference between tops speeds of 95mph and 380mph...a very significant and very meaningful difference.
On top of that, the claims that the 5D III was capable of 30 stops of DR was just flat out ludicrous. Claims that the 5D III can capture 16 stops of DR is ludicrous. The notion that the "10-stop shed lift" resulted in "ok IQ" is also ludicrous...the noise in those images is atrocious, and completely unacceptable.
Sorry, but even though I usually like to defend Canon's IQ for what it is...excellent if no longer "the best of the best", I couldn't just ignore so many blatant misunderstandings and incorrect information lie unaddressed. I enjoy a good argument, and in this case, the Canon guy was wrong, and I responded.
