Sometimes I find it more convenient just to use manual focus when I am trying to shoot single pictures of multiple subjects in a small area quickly such as a flock of birds that you know are getting ready to fly. Sometimes I am amazed at how quickly I can bring a subject into focus.

I shoot Nikon. The front buttons that I use for my D750 and D500 are the Pv and Fn buttons. I use them both for FBF because sometimes my fingers get tired and I also forget which is which, so I programmed them both---I don't need the other functions that they do.

IIRC about my similar Sony [a7-II] which is far
away ATM the real problem is that YOU CAN do
that ... but you shouldn't want to. What I mean
is that [again IIRC] the menu separates things
into two different actions.

One action is to assign AF activation to any of
the user-assignable buttons.

The other action is to enable or disable 'AF by
Shutter Button".

Obviously, there's little point in having a user
chosen alternate "AF-On" button IF when you
hit the shutter release a whole new focus will
occur, overriding the one you acquired using
the alternate AF-On button.

It would be tidier if the shutter button were
de-coupled from AF activation whenever the
user selected ANY other button for "AF-On".
But OTOH by a stretch of imagination I can
cobble up a few sketchy scenarios where a
user might NOT want the "tidier" approach.

I will reiterate that this is all based on IIRC !
I could possibly be thinking of the menus in
some other camera than my Sonys.

I use BBF for everything. BIF are no problem if you use AFS. I will not go back.Your thumb falls on the button with no problems. Happy shooting.

Perhaps on my next camera there'll be something. Meanwhile I also anticipate the focus movement with a slight counter tension with my hand. When I'm shotin my grandson's sports, I get caught up in the action. But perfect practice makes perfect.

I always use it, although I have been known to revert to shutter use at times for fast-moving wildlife. I have used it so long that the wording on my camera button is long gone! I like having the control. You do need to use it long enough to get that hand-brain connection, though, before you go out and shoot something that you really want to turn out. I've seen people in the early stage of using it take a multitude of out of focus shots. Practice, practice, practice to get that hand-brain connection going. Or, just use the shutter if that works fine for you.

Works for me. I am glad that I switched.

It's my primary focus mode, but I have the AF on/off for the shutter release in my quick menu so I can turn it on and focus with the cable when I need it.
