I'd like a high MPix 1 series body for landscape and portrait but you can prise my 1DX from my cold dead hands for what I use it for, 18 MPix is enough, and I don't want to deal with anything over 20 megapixels when I'm shooting over 1000 images a night and have to pp them next day.
There is in my mind a definite need for Canon to produce a high MP Camera, Medium Format but I hope in a 1D Body. Would they survive as a Company if they continue with the current Sensor Line ?? I don't think so, Companies like Canon need to continue to innovate to survive in the Market, there are loads of examples where companies that stagnate innovation tend to Die, Nokia & Black berry spring to mind, Apple now changing their own long held view on producing only for the Market what Apple feel the Market needs, Samsung have clearly provided the impetus for Apple to rethink that view, and they (Apple) have reacted to what the Market wants (Not needs, wants).
I believe Canon were wrong footed when Nikon brought to Market the D800 @ 36MP, I'm not into arguing one Camera company versus another here, only that Nikon jumped a step up on it's competitors with the D800, exactly the way Canon did when they brought to Market the 5DMK II and the Higher MP Sensor with Video ability. This is all a part of the Business of Innovation and a Companies ability to look forward to what the Market will buy, Steve Jobs being in my mind the supreme forward thinker in this area.
Do we need High MP Cameras, not really.
Would I buy one if Canon released one, in a New York second, because I would like a MF Camera, in a 1D Body, that takes the Lenses I currently use, shoots at 6 or 7 fps, and gives me a huge file that I can work on whenI shoot Landscape, Portraits etc. I would buy a Phase One, but I just don't want to get into another system, tried that with the D800, didn't like the experience, tried it with Leica M9, wasn't keen on that either.
Would I get rid of my 1Dx, only when Canon develops a similar frame rate Camera, I actually need the 12fps in my wildlife Imaging, I don't really mind if it's 18MP or 1800 MP, as long as it's 12fps or better and as long as Sandisc continue to develop CF Cards etc with large enough capacity & with fast enough transfer speed to handle the Larger size Files, and as long as Apple keep producing better Computers to allow me to Post Process as I do now.
Look forward to a Canon 1D with +45MP and 7FPS.
