Am I to expect the same 61pt AF system that's in the 1D X?
Considering what Nikon offers, you should be expecting that only even more considering how resting on their laurels and holding as much back as possible and milking out every last penny rather than charging forward and blowing Nikon out of the water (which they easily could have done a few times over the last few years) and arrogant about their position they have become, quite possibly not. But you can hope. Maybe, maybe, maybe, Nikon/Sony have put enough fear into them to wake them up again.
I seriously doubt the 5D? camera will have the same AF and metering as the full 1Dx system.
Again, from the Canon doc on the 1DX, the AF and metering system have a dedicated Digic 4 processor. For the 5Dx to have this AF system, it would necessitate having similar processing power. At minimum, that means the 5Dx would have to be dual processor (Digic 5 for the images, video, and all other functions), and Digic 4 for the AF and metering.
An 18Mpix FF image on a 1Dx at 12 fps is going to push (excluding all other items), 216Mpix thru those two Digic 5 processors. A 5Dx, based on the rumored specs, at 22Mpix and 7fps, will push 154 Mpix thru the processor(s). I do not believe a single Digic 5 can push that pixel load, and handle all other camera functions alone.
If it could, then the 1Dx should be able to push approx 300Mpix thru (based on the 5Dx needs handled by a single Digic 5) and still handle all other functions (except the aforementioned AF and metering using the Digic 4). Now, if that is correct, then the 1Dx should not have to resort to JPEG only in the 14 fps burst mode, it should be able to handle RAWs (the mirror lockup in that burst mode has zero to do with the JPEG only ability of that mode, its the data being pushed that limits it). By estimation and basic scaling of the processors, the 1Dx should have nearly 80Mpix additional bandwidth available for processing.
So, based on this model, the 5Dx would have to have 3 processors to handle the estimated pixel load
, the camera functions, and the 1Dx AF and metering. I don't think that is going to happen. As a result, I believe the AF and metering will be a subset of the 1Dx that does not require it's own dedicated processor.
Don't get me wrong my friend, I would LOVE for you to be right
and it did have the full-on 1Dx AF and metering. I just think that's beyond what this body will have.
