Just to come back to the photographic matter, I would be very interested in such a camera, 5D3 has been for me a disappointment, since I was expecting more from the sensor. I agree the camera is a BIG improvement over the 5D2 about everything else, but it shows that Canon has not done the proper homework concerning sensors. Like it or not, it's always been about pixels, like before we all wanted films with more resolution. IMHO releasing a new prosumer camera with 22MPX priced at 3500$ when Nikon and Sony have 24MPX on consumer DX cameras, looks like it will appear outdated soon. It looks a bit like the D700 that was likely the best camera on the market back then, but every Canon guy was laughing at its 12MPX sensor. Now I agree that something around 20MPX is enough for a lot of tasks.
I understand people want a "do it all" camera, but pro market does not have necessarily the same considerations. IMHO, there is a place for more specialized cameras. The 1DX should fit the task for sport / news people, the 5D3 for event / wedding photographers, but still there is space for a camera dedicated to high quality SLOW picture, like architecture / landscape / industrial / studio photography.
I see a lot of people complaining about low ISO capability or poor AF such a camera might end with. Is it really of such importance ? Does anybody use a GOOD tripod for this kind of pictures ? Because it is a very valuable accessory I strongly advise to try.... Who gives a client a picture of his building taken with 12800 ISO ?
What I mean here is that a few years ago, architecture / studio / landscape were made with medium format or view cameras, that do not have AF, and the only slide film you would have considered was 100 ISO. Therefore I think a high MP camera is intended at a market who doesn't need such features, people who need high ISO or super AF systems already have these cameras with the 5D3 and 1DX. Personally, this camera would have 1600 ISO max and no AF, I could cope with it as I am sure most serious landscape / architecture / studio photographer could as well...
And NO, I can not afford a 30000$ Hasselblad system, so 5000$ for such a camera would be a blessing. I am mainly using TS-E lenses and Nikon equivalents don't really have the same quality as Canon's (except for the 45 TS).
One word as well about the post processing, I see a lot of people complaining about the size of the files and the time required to process them. I can not understand that people who spend 10,000$ on a camera system cannot not afford a decent computer. You can built a PC with 6 Cores, a fast SSD and 16Gb of memory for around 1000$, that will swallow your pics in a few seconds. Personally I upgrade my PC every year or 2, the motherboard / CPU / RAM update is less than 500-600$. Of course for Apple users things are not quite as simple, but this is another debate. Post processing big files has never been a real issue, assuming of course you have enough RAM (I advise minimum 16GB, that's 80$).
What scares me a bit, is that it seems Canon doesn't really have at this time the ability to release a sensor that could match the DR needed by this type of camera, one must admit Nikon/Sony has a much better sensor with the D800. Hope we get more real infos soon.
Now I am ready to get slaughtered but after all it's all about debating.....
