No, but I expect it to focus AT LEAST as good as an xxD, which is over HALF it's price... 40d focuses much better, as does the 30d. ESPECIALLY in servo.
What Chuck Westfall had to say about the 40D Ai-Servo mode.
"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."
