I found this good article and wanted to share it.

Good pointWhen I would scan my Velvia on a good film scanner I would get files that are about 30 MP in size.How much of that 30 mp is emulsion grain ?
The 6D2, will move down market in terms of price and build quality. It is not quite down to "super rebel" standards yet. I think there is a large market for a bare-bones full frame model that can entice people to move up from crop. Current 6D prices are pretty good, but maybe Canon can get the next model even lower? They would be silly not to give it a Rebel form factor with the articulating touch screen. A near $1000 FF model like this would fly off the shelves.

....Thanks for the INFO. But that did NOT in any way answer my question. I suppose most people here are clear that High ISO means low DR When you split in three RGB Monochrome signals it is more than clear that with high ISO you get not so nice images.
"As one example, the selection of a CFA, the color pattern put in front of the sensor, is a choice between quality of color, and ISO performance. If the CFA allows each pixel to see a broader spectrum of color (e.g. for the green pixels to see a bit further into yellow) a camera’s ISO range can be modestly increased. The resulting loss in color quality is subtle – subtle variations in color are missed and a handful of specific colors become difficult to photograph. In a market where a ISO 25,600 camera has a leg up on a ISO12,800 camera, the engineers are under enormous pressure to pick the modestly increased ISO over subtle color quality."
That's really interesting. A claimed advantage of medium format digital cameras have been that they have color-optimized CFAs rather than high ISO, it would be awesome if this sensor has taken the same type of optimization.Actually NO! The trend with MF is to optimize the ISO availability ;-)
I think a 50 megapixel camera for sure should be optimized at high resolution use cases, rather than trying to be a hand-held low light action camera.

However, I suspect that the person referenced is just seeking to help defray the costs of managing a site and trying to cover the costs of one's time is not trivial for some of these sites. A few make a career of it (and when the quality of the content is of value, deserve compensation, e.g. this site or the digital picture.)Even if that is the case - Hosting and similar Cost. Is there a backdoor for that? Otherwise if not officially stated the editorial of such a website/blog/vlog could be considered as pure hobby ergo all costs are not to be considered?
Phase detect - yes. DualPixel Auto Focus however as concept has been made by ONLY one vendor of 4/3 camera.... I believe it was Fujitsu... not sure about the name.That means that they would have to use DIGIC CPUs sensors with DPAF (CANON sensor tech). That means they can't be SONY.
Considering that phase detect on the imaging sensor is something just about every manufacturer does that's quite a bold statement.
Maybe I'm just naive, but who makes RED's sensors, and why doesn't Canon go to them over Sony? The RED Dragon at roughly APS-H size beat out the full-frame Nikon d-810, according to ::cough:: dxomark. Anyone know, does Sony make RED's sensors too?
...And I wonder how do you make a home-grown in-house tech go out to you competitors to produce it? Or you just don't - and that makes you look like everybody else.
One shouldn't expect Dual Pixel sensors manufactured by Sony. No way..... You said it all by yourself:
So probably Canon will manufacture most of their FF bodies with own, home-manufactured sensors and use only Sony sensor for a special high quality (DR, high resolution) body. That makes a lot of sense because high resolution Dual Pixel FF sensor (being effectively 2 x 46 MPix sensor) would generate enormous stream of data that would need processing not only for stills but also video (scaling, denoising etc.) and AF (dual pixel, CDAF).Quote... would generate enormous stream of data that would need processing not only for stills but also video...That means that they would have to use DIGIC CPUs sensors with DPAF (CANON sensor tech).

However, CR might decide not to allow begging on their forums. I see lots of it on ebay. One person was selling a scribbled note to raise money for a new 5D MK III.
