[QUOTE="nickt, post: 717039, member: 4923"] The beauty of bbf is that it gives you af-c focus when you hold the button (good for tracking) and a simulated af-s mode (good for focus-recompose) when you release the button. It ends up being very handy to jump between focus modes like that. I have described it to people as power assisted manual focus. Used with single point focus, you have the ability to put that single point on your subject and either track it or release the button for a one-time focus. If I'm shooting birds in flight I'll either leave it single point or sometimes go with d-9 for smaller birds. Its very important when using this technique that you are in af-c focus mode with menu a1 set to release priority. Some people new to the technique don't get that and leave it in af-s and things don't work the way they read about it. The magic is not that you are using the back button but its that you have the instant ability to auto focus or not to auto focus. Its a lot like manual focus, but with some help. Have fun. [/QUOTE]
