I tried the AF of the 6D last tuesday @ photokina in cologne as one of the very first people. I'm sick of all the complaning about the AF system. The only thing that is not as good as my 5D III is the spread of AF points, they are more in the center of the frame than the ones in the D600, too. But in terms of speed? Seriously, I didn't find any difference in focussing speed with the center AF point compared to my 5D. It was accurate and really fast! there is not that much light at the canon booth and they had not the fastest lens on it (24-105 4.0) and even in that conditions it was totally accurate and fast while focussing pretty dark and structureless targets, also with the other AF points. I think we can believe canon that it can focus in half as much light as the 5D III. I tried the AF for 20 minutes and was pretty impressed. It's a completely diffrent system then the 5D II or 60D, so it doesn't matter if its 1 cross/dualcross/wtfcrosspoint or 10 or 100. It works absolutely fine! So STOP COMPLANING until you had the camera in your hands, took it into dark environment and experienced something completely diffrent!
