Could you elaborate a bit on this, Dave? You've said numerous times that the 5D MkIII's AF blows away the 7D's, and now the 1Dx AF is 10x better than the 5D MkIII when used with TCs and super-teles? What situations highlighted this difference? I ask because I'm toying with the idea of getting either a late model 1-Series (like the 1Ds MkIII or 1D MkIV) or a 5D MkIII so I can use a MKIII 1.4x TC with my 400 5.6 and have AF @ f8. Amazon currently has the 5D MkIII body for $2699, which is the cheapest option of the 3 bodies.

EDIT: Was just rereading a review of the 5D MkIII and a comparison between it and the 1Dx. Even though they share AF systems, the 1Dx has a more powerful battery that drives AF motors faster on some lenses. Hence the faster AF. Is that what you mean when you say it manhandles the AF on the big lenses better, Dave?
