    Very easy to follow article for sure.
    I often thought this was just another thing on my list to learn about, similar to HDR/bracketing.
    Recently I found out it was more of a focus locking feature. Maybe the term 'back focusing' made it sound more complex when it's just really using a button on the BACK of the camera to focus lol

    Good share.

    The article states:

    "The most important thing you need to know about setting up back button focus: you must turn on the continuous AF mode (AF-C) on your dSLR for it to work on Nikon models."

    , which seems a bit inaccurate. I haven't played with every single setting, but have used back button and seldom use AF-C.

    I have back-button set on my D7100, and it works in any AF mode - Although to be honest I only really use AF-S and AF-C with single points.

    It's only accurate in that for it to work the way in which they describe in this paragraph...

    "Back button focus gives you the best of both focusing worlds: single and continuous AF. Keep pressing the back button to use continuous AF if the subject is moving back and forth in the frame, otherwise simply press the back button once to lock the focus. Then, you can take the photo using the shutter button and recompose to your hearts content without needing to keep finding focus."

    ...you need to do it that way. Or, and this is the point I was going to post before realizing I can tack onto this post, you can change the Focus Priority in AF-S to Release. Otherwise, as I talked about in my post about the D750's focusing, releasing the back button and recomposing will not work on some Nikons if you are in AF-S mode and the focus point winds up over an out of focus object.

    It's technically correct, and I think they likely simplified it this way so that they could write about both systems in a common way.

    What I wish is that Nikon had a feature like on Canon cameras where you have the choice of leaving the focus enabled on the shutter button. It's the way it works on cameras like the D800/810 where there is a separate AF button on the back. This way when you hand the camera to someone else they can still use it. It drove me crazy when I was shooting with the D800 and D600 at the same time because they behaved differently when the back button was released. I'm used to it now, but mainly because I stopped shooting with the D800. LOL

    Thanks for the link to that article!

    Even after reading the article, I still don't really see the advantage in using the back button. For those of you who use it, why is it a big improvement? I don't have problems half pressing the shutter button, and it gives me one less step to think about as opposed to using another button. I'm sure I'm missing something, since this seems to be such a popular option to take advantage of.

    Maybe this video will explain it better. BBF is all I ever use, and have used for quite a long time. It's so much easier and faster than regular half press focusing and shooting.

    Re: Back Button Focus - How To Use

    I tried it once for about an hour and it drove me crazy. I then set it back up and gave it a proper test over several days where I was not shooting anything important. After those few days I would never think about going back to the default method. The major benefit I see is that it is so much easier to focus and recompose for me. My fingers and hands don't work as good as they used to so when pushing the button half way I would end up taking a photo by accident.
    I also like that I can do continuous focus by just holding the button down. That is really great when I shoot at the football games on Friday night or I am out shooting and I see a bird in flight or a dolphin splashing around.
