Jim, it ain't bad at all, although I have not done as much of Servo AF tests yet as I would have wanted, however, AF is generally quite accurate with good precision. There are a couple of small nagging issues, but they are not deal breakers.
The X factor is allowing me to shoot in much lower light than ever before, while retaining requisite quality. In fact, I feel the IQ integrity retention with increasing ISO is enough of a reason in itself to get 1DX.
Then there is excellent camera agility and speed.......not much of a fast action can escape 12 FPS as well as practically instantaneous shutter response.
All in all, I believe the effectiveness and reach of 1DX is without precedent.
Here is another shot which might appear as 3D somewhat.
1DX + 500 II + 1.4xTC III.
Another beautiful pijun portrait, I like the frontal water wake images, me thinks of a mad pijun feet paddling furiously, bursting through his watery haven and nipping Peter just a little bit, where I'll let Peter reveal
The 1DX seems like one powerful piece of kit, perhaps Canon actually got something right for most power shooters. Makes me think twice regarding the 6D vs 5D3, AF looks fantastic...who knows, the Mayan calender may reconcile my dilemma
