Reikan has been working on adding Canon EOS 5D Mark III
compatibility to their Focal
software and shared some information on their Facebook page
Especially interesting to me was this paragraph:
"The AF consistency on the 5D Mark III is the *best* I have seen on any camera I've tested with (which is quite a few now!). And it's better by quite a long way - only a few % deviation across 20 shots compared to, say, the 1Dmk4 which deviates by 10-15%."
I'm still giving AI Servo a good workout, but the 5D III's One Shot AF has been very impressive. (thanks John)
