those specs make a lot of sense to me!
The only way to have both camera on the market without killing the sale of the flagship
is using different sensor!
First of all because you don't want again give to the 5D a poor AF !! enough of that!!!
than,if you want to keep the great high iso movie profile that the 5D had,you can't pack to many mp on the sensor and I don't think that after 4 years a 3 or 10mp increase will push the Ds mk II owner to update
I don't see 54mp bee to high for our day sensor tech
2 years old 7D sensor on a full camera will give about 46mp! and that sensor perform really well at iso 3200 and very decently at iso 6400
The only think i can't believe is that in the Dlsr 9000$ flagship Canon can't add Mpeg codec 4 2 2 !!!!
....but of corse in the other hand the 5D is the movie flagship Dslr
I just hope its true!!
MP's on 1Ds4 sound just too high. A canon tech person told me earlier this year that Canon would be working to achieve a 50mp FF sensor in the future with considerably greater iso levels than currently available and a much better dynamic range that almost mats he's the human eye. The indications were that this was not a next generation goal...
But (if my math is right...) a 54 MP square sensor would give you 30 MP if you cropped it vertical or horizontal. That doesn't sound so unrealistic. It hasn't been talked about for a while, but with all the talk there was a couple months ago about different frame rates associated with selectable crop modes, I wouldn't be surprised if Canon were planning an approach where you had more control over which pixels on a sensor you could pick to be used.
