New to the group, Hello everybody. I own a Canon 40D and I am wondering what is the difference between Al Servo and Al Focus. One of my favorite subject to shoot is birds and I am wondering if anyone of these setting will help me in my picture taking. thanks

One is mainly for moving objects, ok, so sport is mainly a moving object, but it is unpredictable, this is why we choose AI Servo

Check page 77 in the manual for a detailed answer. AI Focus is more or less the "auto" mode for focusing type. It will engage AI-Servo if it detects movement in the subject, but otherwise stays with One-Shot.

AI Focus is for people who enjoy frustration.

AI Focus is a combination of One-Shot and AI Servo. Unfortunatley it combines the bad points of each.

AI focus is where the camera tries to guess whether One shot or AI Servo is the best focusing type. Unfortunately, cameras are never as good as humans for deciding this and have a tendancy to get things wrong (addition to Murphy's law - when it does decide to go wrong it will do so in the worst possible way.)

My thoughts for Focus type for birding - AI Servo for Birds in flight, One shot for Birds at rest. Thats certainly the best in my experience with motorsport (not done birding but similar high speed objects)

If there is a lot of movement, AI Servo.

If the artists are fairly static, One Shot.

If you want to be frustrated, AI Focus

All that. AI Focus tries One Shot until it discovers that's wrong, then it goes to AI Servo, just as your subject decides to stop, so it goes back to One Shot as it starts up again and . . . Well, you get the picture.

That about sums it up. AI Focus is about as useful as Auto AF point selection - letting the camera choose what it wants to do, which often has nothing in common with what you're actually trying to do.
