Imagemaster, I know when IS is on or off. When I take some comparison shots and view them back home on my computer, I forget which ones were taken with IS off or on. Maybe I need to bring along a pad and pencil.
I have the same problem, but unless you are doing a comparison test with it on and off, it doesn't really matter.
Forgive my ignorance, but why should I use center point AF only for BIF. I've read some use multipoint for BIF, but they may have more focus points than my XSi.
If you are using multipoint, the camera will focus on the subject with the most contrast that any focus point sees, which may not be your bird if there is something else in the background. Like Gene said, it works best when there is just sky behind the bird. Even then, I still prefer center point only.
I get confused about which are the best AF settings to use One Shot, AI Focus or AI Servo. Many of the birds I photograph are on the ground and then take off. I've been using AI Focus, which I understand the camera senses when to switch between One Shot and AI Servo.
Use One Shot if your subject is sitting still and not likely to move. For all other cases use AI Servo. Forget about AI Focus. I have yet to hear from anyone that it works efficiently.
