From J.R.: Nice shot ... but the point I'm trying to make is that the AF of the 5D3 is way much better than the 7D and will result in more keepers..
Agree, but is there any doubt that the 7D2 will be given the 1DX / 5D3's awesome AF system? Not for me. I think it's a lock.
I'm not saying the 7D2 is getting two DIGIC chips or the 1DX's dedicated metering system, but I think the AF will be top of the line. It's an action camera, so it needs great AF and they happen to have one ready to go. Further, it will commonize the user experience for shooters who bounce between FF and APS-C bodies.
