In the mean time I am shooting great photos and avoiding making sweeping generalizations about my peers.

Well, I did try to limit the generalization a little and of course it's just my 2ct personal opinion in a rumors forum. No doubt you can take great shots with a 5d3, 60d (my current camera) or 6d (my next camera). But imho it's like with all tech advancement, people on the older/current tech often seem to like to stick to the status quo, like b/w->color tv, horse carts->motor cars - you seem to be an exception to the rule if you say you'd like to have d800 specs.

At bottom, a super wide DR gives one a RAW that looks dreadfully flat not gloriously beautiful.

As long as the bit depth rises to 16bit, I don't see any problems with higher dr sensors - dropping data is easy, adding it after highlights are blown and shadows are noisy is another matter :-o

Why you need new Canon sensors like every year? If they pump out something awesome every 5 years im down with that. Would be crap if my new FF purchase would be blown away by next years release.

That's just it - the current Canon sensor tech is 5 years old (5d2-gen, recycled in 5d3/6d) - Canon is bound to make a big leap this or at least next year, if not for the sake of tech advancement then to keep up with the competition. The 1dx sensor with might be the first indication, it has other tech as the iso->dr curve shows.

highest  QE  and DR

Could you please post the link to the 6d dr curve (and comparisons to 5d3/5d2)? Thx.

You can read about different sensors  QE and DR here http://www.sensorgen.info
Thanks for the link - does their testing method include the full highlight recovery available in raw?

The sensor in 6D is the  best sensor from Canon today
... except for the 1dx (as far as I understand the figures).

About 6D. Anyone who uses low-ISO shadows, they will appreciate, like the much lessened banding noise, and if you like to use 800 and above you will like  the  lower noise, including banding noise and if you like  to crop or print large will find more usable and real detail.
I'm looking forward to my 6d purchase (once the early adopters premium is gone) :-) ... that's because if anything really kills my shots on the 60d it's banding when raising shadows, iso noise can be somewhat disguised if the final output size is small.

Can an actual sensor engineer shed light on this matter? It's totally useless comparing a dedicated RED video sensor to a dedicated stills photo sensor, the R&D process is completely different. So what if the RED 4K sensor can capture 18 stops of DR? It's only 8 megapixels (4096x2160) for God's sake, I bet it will absolutely SUCK at taking stills photos.

A couple of years ago I was shooting 8 megapixels on my 20D and doing just fine. Heck, I'm normally on mRAW on my 50D getting 7 megapixels. Go check out some of the photos taken by professional photographers on the Red Epic/Scarlet and see what you think

It is sensor data, and 6D is slightly better than 1dx at base iso regarding DR,  11,5 compared to 11.2

Yes, I saw that, but who shoots at base iso anyway if it's no different from iso 800 except for a little more more dr (and high dr scenes require hdr anyway)? That's why I looked at higher iso levels, and here the sports-oriented 1dx seems to be the best of the bunch by a small margin.

You can gp to http://home.comcast.net/~nikond70/Charts/PDR.htm

Doesn't include the 6d (yet), that's why I was asking for other charts - thanks!
