"D7000 focus reco for BIF" Sat 21-Sep-13 03:12 PM by s2sailorlis_nikon
This morning was looking for hawks/eagles.
Shot this in flight - i was using AF-C with 21 sensors, panned the shot and fired. Focus point per View NX2 was not on hawk, but just below the hawk where the tree and sky was located - just missing the hawk. (see small thumbnail pix below).
Appreciate any advice on better autofocus set up so I would have captured this better...

It might be difficult for the camera to pick the right focus point in a composition that's so loose. What I mean is that the BIF is well within the same potential focus plane as the tree and also very close to the tree as well. So I think in a composition like this, unless you manage to first lock focus on the BIF with tracking engaged before you press the shutter, the camera might not be able to figure out that it's mainly the BIF you want to capture.
I think this is an example, basically, of why so many birders invest in longer and longer lenses and develop all sorts of techniques to get closer and closer to their subjects as often as possible. The tighter you can get - with little else besides the BIF in the frame to distract the AF system - the sharper the photos you're going to get. IMO, anyway.
