Arash, that info does help! From what I have read here on BPN, the 400mm f5.6L is supposed to be excellent for BIF. I am using the 40D for the crop factor and faster fps, but often have trouble getting a bird in focus. My only opportunities so far have been with small birds, so I thought that was the problem. So what I should do is put a longer lens on the 5D MKII for the best performance? I have access to rental lenses (300 f2.8L IS; 400 f2.8L IS; 500 f4L IS).
