I got the 5d2 because I was sick and tired of waiting for the 5d3... going from a 7d to the 5d2 has been very humbling with the autofocus... Quality of file, when in focus, is great, but my lord, the AF in the 5d2 is like putting an Hyundai engine inside a Ferrari... It's truely a shame and I will be liquidating mine once the 5d3 comes out assuming it has better AF...
I am relatively new to the game and photography is a hobby for me... so new that I usually center spot AF my shots (unless I macro, then I MF) . When I hear many people not liking the AF of the 5D2, I cannot understand why (not because I offer a competing perspective, but simply because I do not know better): I am learning yes... but ; can anyone dumb this down for me... how exactly is the AF on the 5D2 not up to what you guys want? Is it just plain accuracy, or slow AF, or the processor's inability to set a multi point focus by increasing DoF or what?
The answer to this might help me make a decision on the 5d2 or 5d3 or even 7d just like the OP.
