OK, first let me preemptively state - I do not like beeps, bells, whistles, or any other cheap consumer-attracting sound effects on anything. I also don't like attracting attention when I am shooting my D800. Having read Darrell Young's and Thom Hogan's D800 books, I can assure you neither of them use this function, and Thom finds the decision by Nikon to even add this to the D800 at least questionable. Both point out that happily the default setting is OFF. So I understand this must not be a very popular function.
Having established that, I personally find that there are times when having an "audible confirmation signal" (aka Beep) when the camera has achieved focus lock to be very helpful. It's one less thing I need to assess visually in the view finder, so I use it.
However, I just discovered that this function is deactivated if I change the a2 AF-S priority selection from Focus to Release mode. Everything else works like it should, including the appearance of the green circle in the viewfinder, but the beep no longer sounds with it. It only works in Focus priority mode. I tested it in Live View and the same thing happens. I also checked and the beep does continue to operate for other things, like counting down the self-timer.
I checked both Darrell and Thom's books, and the owner's manual, and clearly it is only an AF-S function, but no one makes any distinction between Focus and Release priority settings for it. It doesn't make sense to me that it would not work equally for both. If fact, it's more important in Release priority since you're more at risk of taking an out of focus image.
Is this just a glitch in my D800, or is it programmed like this in everyone's? If it is this way in all of them, am I missing the logic of why it should only operate in Focus priority and not both? If so, what is the reason? Or, do you agree that this is probably a problem that should be picked up in a firmware update?
Your help will be much appreciated. Thanks in advance.

Thanks for the reply Hans. It's no big deal to me, I am just trying to learn the camera and want to know why things do what they do. It seems like a software glitch that Nikon may want to clean up. I put the question into NikonUSA on Friday, but haven't heard back. When I do get an answer, I'll post their response - for what it's worth.
Both my D800 and D7000 operate in the manner that you describe, so it is not a glitch to the D800. It appears to operate that way by design. Hearing the beep after your shutter has released might be disheartening..
Thanks for the info Jim. As long as it's by design that's OK.
I shoot my D800 with the autofocus solely handled by the AF-ON button, and the shutter release button only releasing the shutter - a4 AF activation is OFF. This may be why I like extra confirmation of achieving focus lock before I even touch the shutter release, since it plays no role in focusing with my setup.
I did try toggling the a4 setting to ON and OFF, and it made no difference on my question.
Thanks for taking the time to check it out for me. I appreciate it.
One thing new with the D800 is...when you set AF-ON ONLY (a4 on menu) the focus priority feature is deactivated.
On my D700 and even the D7000, the focus priority feature still worked when AF-ON ONLY was set. I believe that was true with other models as well. It used to save me from some premature shutter releases... Oh well.
Jim, On my D800, with a4 set to OFF / AF-ON ONLY, a2 AF-S menu still allows the choice of Focus or Release priority. And they both work like they should. To check it, I tested them by manually setting the lens at infinity, pointing the camera at something close up and pressing both buttons simultaneously and held them down. With Release priority the shutter released instantly, and with Focus priority the shutter delayed until focus was achieved then fired, which is what I would expect.
In all my reading on the D800 I've never come across anything that mentioned losing the focus priority feature when you select AF-ON only. Double check your D800, you might be in for a good surprise!
You certainly can set FOCUS priority on the D800, whether in AF-S or AF-C focus mode and AF-ON ONLY. However, the D800 operates differently than earlier models (such as D700).
The D800 shutter will release, while in AF-S and FOCUS priority, whether anything is in focus or not. This is a change from earlier camera bodies that required the camera to be in focus (you could over-ride FOCUS priority on earlier camera bodies though).
That is what I meant by deactivated. The setting does not function on the D800 like true (past) FOCUS priority.
There is a discussion about this change going on now, on a fairly recent post.
Jim, Thanks for the clarification - my misunderstanding. That's interesting about the change, and you have my curiosity up. But I will chase this down on the other post; I don't want to get too far off subject from my original question on this one.
Thanks again for your help. I really appreciate it!
