[QUOTE="WayneF, post: 370996, member: 12496"] Well, it does sound broken. :) Ever since we had had auto focus, cameras would lock focus and exposure if we held half press, so we could recompose at will (while holding). Even compact cameras do that. That's how, if the subject has a bright window behind them, you can focus at their feet (to exclude the bright), and hold it to bring it up to their face for a reasonable exposure. That is how D750 manual pages 129-130 describe it still working. So there must be more to it, some other interference. I'm guessing something about AL/AE. See page 362, possibly AF-ON may disable it? I already knew, but I just checked my D800. AF-S, focused up close, and holding half press, then if aimed far way, the green dot in viewfinder disappears, but the shutter still works, focus still locked close. That's just how they are supposed to work. [/QUOTE]
