BBF - (Back Button Focusing) - I like it.

I've been using BBF exclusively for many months now and love it.

It allows me to use the AI-Servo mode for focusing but control when it is active totally independent of when I take the shot.

So I can choose to focus on a person's eyes but quickly recompose the shot without having to choose a new focus point.

I can quickly have the effect of using manual focus without changing any settings.

Now that I am used to it I could not easily go back.
