\"Autofocus The 5D Mark II\'s AF system, including its CMOS AF sensor, carries over mostly unaltered from the 5D, and is comprised of nine AF points plus six Assist AF points...
...Somewhat surprisingly, Canon has not adopted the 40D/50D\'s AF system which, on paper, is superior, given that all nine of its AF points are cross-type. Canon USA\'s Westfall says the reason for that is the \"6 Assist AF points plus center point were deemed to provide a higher level of performance for AI Servo AF than the center point-only arrangement of the [40D and] 50D.\" Given that we\'ve previously found the overall autofocus performance of the 5D to be decent, while the 40D\'s tracking capability has been erratic at best, Canon has likely chosen the better of the two AF systems for the 5D Mark II.\"
Hmm... Interesting phenomenon. I wonder what that bodes for future pro-level AF?
Probably one center AF point that can be turned on/off and 44 invisible and non-selectable assist AF points. What a BS... Basically he says the 5D AF is better for AI Servo than that of the 40D/50D. I wonder if he ever shot with these cams himself... Marketing c@#$. Or maybe true... which is a bigger fart.
