So in this thread, you personally linked to a test done by naturalexposures.com: http://www.dpreview.com/forums/post/53604443

I looked a bit more into it, and this is what I've found on CAF on some of the Nikon tests he did. I threw out GH4's 0 pointers since he didn't do it for his Nikon tests, and would put the Panasonic at an even more disadvantage. %1 is his 5 pointers divided by the total. %2 is his 5 and 3 pointers divided by the total.

Mirrorless cameras are quickly improving, but as you can see, unlike what you seem to be claiming, they aren't there for CAF yet.  Do you disagree?

GH4
1 - 47
3 - 12
5 - 72
T - 131
%1 - 55%
%2 - 64%

D4
1 - 36
3 - 11
5 - 109
T - 156
%1 - 70%
%2 - 77%

D800
1 - 40
3 - 13
5 - 102
T - 155
%1 - 66%
%2 - 74%

D600
1 - 28
3 - 15
5 - 50
T - 93
%1 - 54%
%2 - 70%

Also, for your future reference, the word "please" isn't used in English as you've been using. Maybe you mean, "Sincerely" or "Yours truly" or even "Thank you."
