I have a Nikon D3100. I have found that it works in every mode except auto. I have to use the shutter button, when I switch to auto. Unless there is a way to do it that I have not figured out yet.
Try this search on GOOGLE "Nikon D3100 BBF"

Dave, You might want to watch a video about how to set BBF and then check your settings; BBF does not get turned off. Search GOOGLE for "Canon T2i BBF"Thanks for the idea. I just tried it on my Canon T2i; I have to switch it to Auto, however, for the BBF to switch off. Still, that's fine for the other person taking the shot.

I guess you have the answers to your questions by now. The purpose of the back button focus is to separate focus from exposure which at least for me makes it very convenient.
It can be used in any mode you want to.

This is a different Dave, Could you possibly show where there is information about BBF staying on in all Canon modes? Every Canon I own has the BBF feature
programed in and in every instance when camera is set to auto the BBF is turned and the focus goes back to the shutter release. This is a great feature BTW, as
if you give your camera to someone to take a photo you will not have to explain the BBF. It works like every other camera
Thanks in advance for the info

I own a Nikon D7200 and exclusively used BBF. Just a word of caution though. My wife and I love to travel and often we find ourselves in front of some famous landmark and often we have our picture taken in front of that landmark. Giving my camera to a fellow traveller or trip leader, I have on occasion forgot to mention that I use BBF and, of course, they just assume the shutter button will automatically focus the photo. Because I failed to mention I use BBF (and specifically point out what button to press) we've had a few photos out of focus. It's the little things that can save some disappointment....

First, yes, BBF will work in the three modes you mention. But it will not work in any of the automatic modes like full auto, or any of the other auto modes.
Second, for a landscape, you focus where you want to focus. You adjust your aperture where you want to set it. There is no setting that is perfect. But if you ask me, somewhere between f/8 and f/16 is good, and many say to focus on the foreground about 1/3rd of the way out. I don't do it that way; I usually focus on the subject which could be the mountains, or it could be something in the foreground.
Last, the only reason to not use BBF is if you want someone else to take your picture with your camera, or if you have a Canon 5D Mark IV and want to use the LCD touch focus, or if using a remote shutter release and you want it to be able to focus when you do a half press.

I always use BBF, it took me a while to get used to but I like it much better, once I focus on a particular subject I can reframe, easy peasy.

It's happened to me (and my wife) too! But the people who offer to take the photograph generally have no clue about DSLRs so I let them take it because (primarily, I'm not spending any money on a wasted shot) they seem so nice in making the offer to photograph us together.

I, too, am a BBF devotee. Using the shutter button was annoying being I lack the grace and magic touch to focus that way. Every third shot would be out of focus because my fingers would press down and press down hard! The first thing I do whenever I get a new camera is set it to BBF.

That's one reason I was looking for input on BBF. I found the shutter a bit awkward. Sometimes pressing to focus and the shutter would take the picture.
Just fiddling too much to get the right touch on it.

If you do focus and reframe - your subject must NOT have moved in order to still be in focus !
If you are left-eyed, the back button placement impedes it's use.
Using BBF requires a form of multitasking - which slows you down as you age - if speed matters

It was a major improvement on performance and usability.

Sorry but I'm feeling a little dense here. What is the major advantage to using BBF? The camera has to focus whether it's BBF or not. What does BBF buy you? I own a Canon 7D MK II and it shoots 10 fps whether I use BBF or not.

Once set, BBF is for ALL modes, all the time.
Once I found out years ago my camera would do it, I set it and never went back.

That's how my D750 is. It runs all the time in all modes.👌
