Canon will make far more money selling the top end kit to wealthy hobbyists than they will to professionals.
I think there is a lot of truth in that statement. Professionals buy tools that are good enough, reliable enough, cheap enough, ... enough, to be able to make a profit. Enthusiasts, not being concerned with profitability, can afford the "bestest and latest".
Agreed with the above, but......
I make a living from Photography, and although the new 5Ds is rather steep for me, and I probably wont get my money back quickly, I would get it nevertheless..why?
Because its just such a lot of pixels that as a photographer I have to have it, just to see what the image quality is like. I find a lot of photography 'ignorant' clients often ask me how many pixels my camera has...and they usually raise their eyebrows when I mention (just) 20mp, imagine the reaction when I say 50mp's! I know its silly but one has to at least try and have a better camera than the client!
I also have a 44inch printer and frankly my 6d is just not up to the task with more detailed images like distant landscapes and industrial/architecture. Jaggies are quite visible. Clients like it a lot when I drop off a 'free' print of the shoot, and the bigger the better and extra pixels can only help...
For my personal stuff which is mostly documentary architecture I could see the extra detail will be great especially on large prints!
Its a lot cheaper than med format digital. Sure it wont have the same image quality but it will be a lot more than is currently available in 35mm, specially from Canon..I also just don't like having too many different systems...so if it can all be Canon, great.
50mp is not just for printing very large but also for making smaller prints look better...there was a reason many 'old' 8x10 negs were only contact printed...
The fact that it has dumbed down video and no dual pixel af is ok by me...its that sensor that I want.
The price seems reasonable for the pixels. One reason I wasn't keen to get the 5D3 is that I could get the same pixels in the 6D for a lot less...
I also like the fact that they have made an effort with the mirror. My Mamiya digital med format shutter slap is alarmingly loud and definitely affects my image quality on longer lenses at slower shutter speeds.
So, I am very excited about the new nifty fifty...and I look forward to pairing that with one of the smallest and cheapest lenses available...the 40mm pancake. But also with my 24TS..should make a fantastic architecture/interior/industrial combination.
The only thing I will miss terribly is GPS and wifi....but I can see using a camera like that for at least 4years. Thats how long I had my 5d2. 6D is now about 14months old and I just love it..only thing I wish it had was a few more pixels.
