[QUOTE="BackdoorArts, post: 371140, member: 9240"] Just got back from shooting and think I have it figured out. The D750 definitely behaves differently from the D610, which I'm assuming has everything to do with the different focusing systems. I have both cameras in AF-S Single Point and the AF-S Priority set to Focus, both with the AE-L/AF-L button set to "AF-ON". With the D610, I use the back button to choose my focus point by pressing it in and achieving focus and I can then release the button, reframe and fire, with the camera taking the photo with no problem. With the D750, once the button released unless the focus point is over something that is [I]also[/I] in focus the camera will not fire. In other words, I can focus on something, release the focus button, reframe, press the shutter release and nothing happens - it [U]will not[/U] take the photo. But if I move the camera around with the shutter button down and as soon as I pass the focus point over an object in focus it will fire. If, however, I maintain pressure on the focus button everything works fine. I went back and rechecked and [I]every[/I] previous Nikon I've had will allow me reframe and fire without keeping the back button pressed - the D7000, D7100, D600 and D610 (but not the D800 since it has a separate AF button on the back that maintains the AF function of the shutter button, so if you reframe without maintaining pressure on the AF button it will refocus before firing). I suppose it begs the question (for the curious at least), "Why did I start releasing the button during reframing?", and I suspect it had something to do with using AF-C mode with birding and then finding a static object I wanted to shoot and in reframe. In AF-C, focus would change during reframing because that's how the mode works once locked, so I likely learned to release when reframing a shot so being in the "wrong" mode wouldn't impact focus in a way I didn't want. Summarizing, I am [U]not[/U] saying the camera isn't working properly - follow the AF Lock reframing instructions in the manual and it works perfectly. What I [I]am[/I] saying is that it does behave differently than the other cameras that do not have a dedicated AF back button. One more thing to remember.
