In the wild?
There’s word that Canon is sending out test bodies of the next 5D to various key photographers. Obviously they’ll be under a veil of secrecy. Once this happens, we tend to start getting better information.
There’s a thought the next 5D will not push megapixels, but will in fact push image quality and noise reduction. There will be a lot more sharpness and detail at higher ISO. The 26-28 megapixel range is becoming the resolution I keep getting told.
There is apparently a couple of different prototypes in existence.
What’s for certain is it will have a 19 point AF, no word on how many crosstype sensors.
1Ds Mark IV / 1D Mark V
The same person alluded to the merging of the 1D line being sooner than expected. There would need to be some new tech in a merged 1D to keep the 10fps of the 1D and the resolution of the 1Ds. It should be interesting.
