With slow wing beats the Eagle took a short flight between two trees after being herassed by a couple of Shikras.

The 5D did a good job of locking on to the bird despite a busy background. Normally I use the 1DMkIIN for flight pictures and was a little worried that the 5D shouldn't be up to it.
I really appreciate the high image quality and the large viewfinder of the full frame, one notch better than the 1D and miles better than the 400D.
