Hopefully so, John....there is a huge qualitative difference between trying to focus on anything that \"flies by\" (i.e., minor/slow focusing distance change) and something that flies/runs/drives fast straight towards the camera (i.e., major focusing distance rate of change).
The new AF system (1DX and 5DMkIII) certainly holds promise in that regard.
Here is another example, although this kinda rough shot difficulty \"rating\" may appear rather abstract for non BIF shooters.
Slow flight (0), no AF diverting background (0), moderate head-on speed component (0.5), large bird in VF (0), fast lens wide open, although in this case it didn\'t really have to be (1).....
all that gives a BIF difficulty level of 1.5.
1DMkIIN + 135L wide open.
