both, I used Nikon previously then got a couple of 1Ds which i started using and bought more lenses for and really liked so decided to sell all my nikon gear and consolodate onto canon I assumed that the AF would be similar to Nikon accross the range boy was i wrong, I am getting used the the quirks with the 5D2 AF but really on a camera at this level they should have made it better, 9 points i dont even have a problem with the number so much as that the other points are completely ineffective in very low light for example shooting low key in a studio with another photographer using a D7000 i was using the 5D2 and the 24-105f4 he was using an 18-105 i think on the D7000. I could not even achieve AF lock when setting any of the outer points with the 5d2, center point was ok though, so i changed to the 1D and it could lock on with any selectable point. the D7000 had no problems achieving lock. And this is shooting static models in a controlled environment. So now i basically use the center point only unless i have good light on the 5D2 but i find myself just focus and recomposing alot more and just using the center point only.
I was also having problems with the 5D2 consistently back focusing when using AI servo with someone walking toward you.
I really hope canon pick up their game with the AF on the next round of models its the only real let down with the 5d2 IMO other than that i love the camera and its IQ size and control layout
