    I tend to use BBF when the part of the subject that needs to be in focus is rather small,like eyes.

    It is easier to lock focus before concentrating on composition.Some of the time I also use AEL too,which is set to toggle.

    I tried that for a while, and it's a perfectly sound approach, but it just didn't suit me - so BBF it is.

    My previous reply was frivolous. It is true that before AF, photographers captured moments of action using the focussing ring, either actively or to prefocus. A lot of shots were missed due to poor focus.Using a modern AF system and bbf I suspect that less shots are spoilt but don't ask me to prove it; I don't really know.
    I find that oscillating between bbf and release focus is confusing. I find it best to set my DSLRs to bbf and leave them there. Backbutton focus has become second nature for everything, whether it is needed or not. As I have mentioned earlier, I don't care how other people focus; that is their affair entirely.
    When you pick up your camera, how do remember the state in which you left it? Back button focus never is harmful, even when it is not required. Release focus is also fine. An indeterminate state leads to lost shots.

    If and when I'm using an autofocus mode I do use BBF because I never seemed to be able to only half-depress the shutter release - so I was taking shots rather than focusing the camera and more of them were a blurred mess than I wanted.

    Yes, that's certainly among the reasons that I switched to BBF - however, mainly it was due to unwanted re-focus, and to simply focus/recompose.

    Nor was I being entirely serious. Also, a great deal depends, quite simply, on what you are used to and what sort of pictures you take.

    Cheers,
