For my shoots, the 1d Mark III provided much better AF than the 5d2.


With just the center point in good light with an f/2.8 lens and a high contrast target, the 5d2 is pretty fast and I get a good amount of keepers. I get poor results if I use a slow lens, non-center AF points, low light, or low-contrast target. In those circumstances I try to shoot burstmode and bracket focus with the 5d2. The 1d3 in the same circumstances excelled. (I did not tend to use the 1d3 in the ways that caused everyone else to have problems).


The kind of shoots where I use AF is event photography such as weddings. I think a 1D autofocus system works much better in those circumstances.
