    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.
    I view it as a better way to 'lock in' persay. When shooting sports, I find I sometimes press too far down as I'm waiting for the shot to come into play.

    I'll mess with it during this weekends games.

    Shoot in the cold, with a pair of gloves, and see how often you accidentally fire instead of locking focus, or miss a shot because it wouldn't press down. Two buttons, one function each. Until I shot with gloves I didn't see the big deal. Now I can't shoot the other way.

    Re: Back Button Focus - How To Use

    I discovered the option in the settings but always wondered what the use of it was. Until I watched the video linked here.

    I switched yesterday and still occasionally push the trigger while at first wondering why the cam isn't focusing but when I'm doing it right, it is great. It has enormous advantages while I'm shooting birds now. If I keep it pressed, the focus keeps tracking my subject and I trigger whenever it is worth it. If they land somewhere, I only have to release and my focus is locked. Even while tracking, if I spot a better target, I release, switch to the next and press again to track that one. No more accidental shots or loss of focus by lifting my finger just too much.

    It'll take a while before I am fully used to it but I'm already certain I won't switch back.

    Re: Back Button Focus - How To Use

    Hello, I quite like the back button focus but on my D7100 if assign the AE-L /AF-L button for focus I find that I lose the ability of autofocus when i use a remote cable release. Is there a setting I'm missing and does anybody assign the Fn button to focus. I have tried that too but I find the button a bit inaccessible.

    I never had much use for it before since I either focused manually or did stationary but when the target moves, it makes all the difference. The only thing I now still need to find is the best focus option for this. Single focus point works well but you'll lose the target easily while more focus points can confuse the cam the moment there's too much in view.

    Re: Back Button Focus - How To Use

    Hi, re my earlier post, my question still stands but I have found a semi solution in that if I set user settings on U1 to my settings including Back button focus, then I can set U2 settings to normal shutter release focusing and therefore remote cable release too. I would still like to know if i am missing something in the settings that lets you use both back button and normal focusing.

    Hmmm. Generally when I'm using a remote release I've already prefocused and turned any autofocus function off. I do know that the camera will attempt to focus with the ML-L3 IR remote, but I have no idea what will happen with a wired remote. My Vello has a 1/2 down function to allow for autofocus, so I would assume that this would engage AF regardless of which button it's set to - but I just tried it on my D610 and no, it won't focus with the AE/AF button set to AF-ON.

    I don't know how changing a different button to focus would fix that (you can set the Fn button to AF-ON on the D610). If you're using a wired remote I'm thinking it's likely just easiest to either reset the AE/AF button before using it, or prefocus and then turn AF off since I suspect the reason you're using the cable is to limit camera movement.

    Did you try and switch? I'm hooked to the back button. I was walking the dogs today and had the cam with me. By using the back button I could easily shoot single-handed while still holding the dogs with the other. When pressing, you automatically tighten your grip. I also fully switched to group focus to track. It's a slightly bigger area than the single point which improves staying on target but it isn't that big the focus jumps to something else.

    It makes capturing flight so much easier.
