I would suggest you look at the new 7D, it has a very much improved 19 point focusing system and its fast. I have one but still in the testing mode with birds in flight and Wow! what a difference from earlier models.
The expanded spot focusing with A1-servo for keeping fast moving birds in focus works like a dream but like I said I still have a lot more testing to do.

Check out what other people are saying about this Camera before making a final decision on switching. Eventually I will put review on what I really think about it at the moment I am still in the Wow! I didn't know it did that stage.LOL!
