I just upgraded from a D300 and almost always shoot with AF-ON. On the D300, AF-ON only triggered focus. I still had to half-press the shutter release to trigger VR. I actually liked this because it saved battery power while I was tracking a subject prior to shooting.
On the D800, AF-ON now triggers VR. Is this unique to the D800, or does it happen on other more recent bodies? Any way to make VR activation go back to the shutter release button only?
D700 is the same as the D300 and D300s (AF ON only does AF not VR). I'd also prefer the D800 to make it a menu option but I don't readily see any. I also prefer the two to be seperate. When the subject is about to be obscured, I can let off the AF ON button and then pick it up when it reappears, ready to shoot by holding VR on with the shutter release. Now, I have to wait for VR to re-engage which is usually longer than a minor focus change. I can see this being one of those little mental hiccups when switching between the two cameras.
Edit: After a little thought, since the shutter release halfway also still activates VR, my above scenario will still work. I just have to not get in the habit of relying on AF ON for the VR activation. But yes, it will take down the battery faster.
This would be a fairly LARGE DEPARTURE from current functionality. Personally I would prefer it But I would prefer if this were the case that a YES/NO option also be available for those who wanted the functions separate as they are on other cameras.
But I did a search and I couldn't find any documentation indicating this is now the case? Edit: To clarify I couldn't find documentation one way OR the other.
I did a pdf search of the D800 manual and could not find anything either way as well. But, I have little doubt that my D800 is in fact performing in this way. I can hear it and I can see that the viewfinder is being stabalized. I tried with multiple lenses. The AF ON button activates VR and so does a half press of the shutter release. This is the case whether or not you set the AF ON button to be the only AF button or leave as default (menu item a4).

Perhaps they have made it, because you can set the VR off on the lens, then it will not drain the battery = then it is equal if you use half press or AF-ON, and you shall only remember to set off and on ...on the lens ?

Yes you can turn it on/off on the lens. But that's wholly impractical when you're talking about actively shooting a subject. My preferred technique when handholding with VR is to use AF-ON to focus track a subject and meter. Then when I'm ready to shoot, I half press the shutter to active VR, finalize my composition, and take the photo. There is no practical way of doing that by using the lens VR switch. This should be something that could be addressed with a firmware update, but Nikon will have to get a good amount of feedback to make it happen.
I remember a number of items on various wish lists on forums regarding people wanting this feature. Maybe Nikon did not take a wide enough poll but a lot of people are going to prefer a stabilized VF image and lack of delayed setting time. I think I will prefer it as well. Stan St Petersburg Russia
I shot a MotoCross Event today with my D800 and 28-300 Nikkor. Two months ago I shot at the same track with my D5100 and 28-300. I am not only amazed how much better the pictures turned out but also how much better the lens worked on the D800.
I have the AF-ON set to be the only button to activate AutoFocus. The VR worked just like it should and also nearly as fast as the 70-200 I used during practice.
I switched when I realized 70mm was not wide enough for the start of the race and that 200mm was not long enough most of the time.

You know what... it does. My apologies.
I do not normally use VR for my shooting, but had recently and I did not remember hearing the VR come on with my AF-On button press. I just did a verification by putting my 70-200 on the D800 and in fact the AF-ON *DOES* start the VR.
I think my confusion stemmed from the fact that I used that lens on my D3s most recently, and my 300mm/2.8 on my D800 and that lens does not have VR.
So yes, this seems like new behavior. For me, it's a benefit, but I can understand why for some this would be detrimental in terms of battery performance.
