[QUOTE="dieselnutjob, post: 717010, member: 47318"] I just upgraded from a D3100 to a D750 (about four weeks ago). The D3100 rarely came out of Auto mode, but now my daughter is doing wonderful things with it so I got to upgrade. One of the things I saw in Tony Northrup's wonderful tutorial ([URL]https://www.youtube.com/watch?v=GmT4wVNTTjE[/URL]) was Back Button Focus. Having tried it I kind of get it, especially for focus and recompose, but I'm not sure that I'm 100% all in on this. After enabling it I then (later on) found myself forgetting to focus. So then I thought, is there an easy way to enable Back Button Focus (BBF) only when I want it? The only answer I found is to program it into one of the U1/U2 settings. So for example I can put the camera in P mode, set BBF off and save to U1, then set it on and save to U2. Now U1 is P without BBF and U2 is P with BBF. All of the others (Auto, P, S, A, M) also now BBF on because that was the last one before saving it. If I had set BBF on and saved it then BBF off and saved it then I think that would make BBF off the default, is that right? Anyway this seems a little clunky because now suppose I want to reassign the record button to ISO, I have to now save that to U1 and U2 as well which "overwrites" the BBF setting in one of them, so I kind of have to do the BBF on in U1 and off in U2 again. Is there a cleverer way to do this? I guess I want an easy way to temporarily use BBF just when I want it? and maybe I want that way to work in all of the modes (Auto, P, S, A and M), and really I suppose I would want continuous focus on as well, and maybe go back to single focus when BBF is deselected.
