The AF module is the same, the only difference is the 1dx has a more advanced metering sensor that feeds colour data into the calculations.
Do you have any link to a reference that they have the same AF sensor module? Per what I have read somewhere, even though they both have 61 AF points, but they're not 100% exact same. I'll have to look up. Anyway, please give me a reference in case I'm mistaken. Thanks.
"The 5D Mark III has a 22MP full frame sensor in a body that's based on the EOS 7D design, and with a 61-point AF system borrowed from the flagship EOS-1D X."
I really can't see how the 5D3 and 7D can be described as having a limited feature set. Of course you don't get everything the top series have. That's why it's called thus and priced accordingly. What do you want, all 1-series features in half the price? Get real.

Happy shooting,

Regarding the 5DMIII, spot metering on just the central AF point comes to mind.
I could be wrong but AFAIK, spot metering does not require additional hardware, i.e. it's just software (the hardware part is already there anyway).
"The 5D Mark III has a 22MP full frame sensor in a body that's based on the EOS 7D design, and with a 61-point AF system borrowed from the flagship EOS-1D X."
"The 5D Mark III's AF eclipses both, gaining the 61-point AF sensor from the company's flagship 1D X. "
"The 5D Mark III uses the same AF sensor as the more expensive EOS-1D X."
And the very same review says, "The 5D Mark III comes with a new AF system that is, in terms of specification, very close to the flagship EOS 1D X." (This review was written before the 1D X got the firmware update.) So, why say "very close"?
I recall the 1998 EOS 3 was designed to AF at F8 with center point and in single axis configuration only (no cross). It was the first EOS designed to focus at F8 and not a 1-series. Back in the day I tried my EOS 3 a few times with the 400 5.6L and 1.4X extender and the results were pretty terrible in all but the brightest light. Unless F8 AF kicks arse, it would be better to leave it off...

That's the thing, many people have tested out that f8 focus and it can work well on the 5D3. I use it for birds in flight shots. It has to be pretty decent if it works for birds in flight shots. Being able to use the higher quality canon extenders should only help performance.

I'm not dismissing what you claim, but I don't think I would use that as a reference.
Because we KNOW it isnt the same whole entire system. Because the 1Dx uses its bazzilion pixel colour metering system to track moving targets, and the 5d3 doesnt.
It has the same AF module, it just lacks the same metering input, which should have no bearing on f8 focusing.

Now Yakim there's no call for logic in this debate.

The 5D3 is 95% of the 1D X at 60% of the price. So some things are missing, yes, but that's what it is. But from here to call it a camera with limited feature set is grossly exageratted.
