It's got the functions, but that is it. The AF module on the 1Dx and 5DII are light years ahead of the 7D II. I for one am very disappointed. Just because of that I will never buy one.
I presume that's the 5D3 not 2? The 5D3 AF was a disappointment to me as they decided not to include the metering sensor tracking assist from the 1D X, even if it has the rest of the stuff, that would have been the selling point to me. I suspect it would have put the 5D3 rather too close to the 1D X at the time. Thus for my uses at least, the 7D2 is on paper miles ahead of the 5D3. Of course, it remains to be proven in use. Anyway, now the precedent has been set, it seems likely the 5D4 will get a similar upgrade whenever that will be.
In general, I wonder if it would be fair to say those that like the 7D like the 7D2. If you didn't like the 7D for your uses, the 7D2 isn't likely to change that.
