I'm really tyring to get a good grasp on this whole BBF thing. I like being able to lock the focus without using the shutter, but I'm having a heck of a time getting focus when in AI Servo. I read a TON on the subject but every new thing I read just confuses me more. I take a lot of pictures of my almost 6 month old son and he's all over the place. I was under the impression (from reading and more seasoned photogs) that AI Servo would help with this. Unfortunately, I'm getting crap in return. I'm holding the button down and tracking him as he moves. Should I not be doing this? If I just press and release, focus is locked but obviously that's not going to get me a focused shot since he moves immediately after I lock focus. Soooo, I hold the button down then press the shutter while holdind the * button down. Is this wrong? And I really apologize if I somewhat covered this topic in another thread of mine. I would loooove some clear advice. I am taking this whole photography thing very slow and know that this is one area (focus) that I need to have down pat before moving on to other areas. Thaaaank you kindly, sirs and madams!
