I owned the a99 when it was first released - there's no way the AF is anywhere near the 5d3 with all those AF points crammed in the middle, let alone the AF tracking. They're not even in the same league; Canon's AI servo vs. Sony's "focus on the background" AF. Just no comparison.

Would you like artificial butter flavoring with that popcorn?
yes, but the D800 must have the better AF because it was "based on" the D4, and we all know that anything "based on" the D4 must be accepted a priori as superior to everything.
What we need is the Dxo score for AF systems. that would be the artificial flavor

Except the 5D Mark III AF was "based on" the 1Dx... ;D

of course; everyone knows that, and I was trying to avoid the corresponding illogical comparison of The 1DX and the D4 in this context: To point out that the 5D3 AF is based on the 1DX contriubtes the same as saying the D800 AF is based on the D4: Nothing.

FYI
Having been employed for 20 years by a major conservative high tech Japanese company, one needs to understand the concept of KAIZEN in Japanese culture.
“Kaizen is a system of continuous improvement in quality, technology, processes, company culture, productivity, safety and leadership.
Kaizen was created in Japan following World War II. The word Kaizen means "continuous improvement". It comes from the Japanese words 改 ("kai") which means "change" or "to correct" and 善 ("zen") which means "good".
Kaizen is a system that involves every employee - from upper management to the cleaning crew. Everyone is encouraged to come up with small improvement suggestions on a regular basis. This is not a once a month or once a year activity. It is continuous. Japanese companies, such as Toyota and Canon, a total of 60 to 70 suggestions per employee per year are written down, shared and implemented.
In most cases these are not ideas for major changes. Kaizen is based on making little changes on a regular basis: always improving productivity, safety and effectiveness while reducing waste.
Western philosophy may be summarized as, "if it ain't broke, don't fix it." The Kaizen philosophy is to "do it better, make it better, improve it even if it isn't broken, because if we don't, we can't compete with those who do." ” By Steve Stephenson
The problem with KAIZEN is, when your competitors make a quantum leap in technology and/ or quality control, there is a catch up period and at times it never happens.
Sounds to me like the CANON culture.

This is the first time I have seen a serious claim that the D800 AF is equal or better than the 5D MkIII AF.
Roger Cicala of lensrentals tested and found that the Canon's phase detection AF is as accurate and consistent as its contrast detection AF, i.e. the standard deviation of MTF values of a series of static shots is the same for both AF systems. This is a remarkable achievement. The D800, 'nope'. It is just not as reliable on phase detection.
And that is with static subjects.
He also says there is a left side AF sensor issue with the D800 that is unresolved, and recommends the camera only be used for centre point AF. I hope THAT isn't 'based on the D4'!

+1 fwiw I haves used the D4 and I can't say anything bad about that AF system, it didn't miss one single shot. This was before I got the 1dx, but I wouldn't say one is better than the other. I didn't test the D4 like I have used the 1dx, but it simply worked perfect. And the d800 is not even on the same planet.

Why don't you direct that very silly and irrelevant comment to Roger Cicala -- it is he who you are taking issue with (although I seriously cannot see the issue in my post that you are taking issue with. You simply haven't said anything except "I wanna have the last word, boo hoo"). ;D
(space provided here for the very silly last word about how he agrees with Roger Cicala but disagrees with me when I quote Roger!
