That varies depending on what camera body you are using.
Newer Pro Nikons like the D4, D4s, D800, D800E and D810 will all activate the VR using the AF-ON button. Older models will not. Models that you need to program the AE/AF Lock button for back button focus also will not activate the VF.

Do you know if it works on the Nikon 610? Since I broke my wrist and arm, I dont know if its me or the camera. But with BBF and recomp, the area I focused on is not as sharp as I would like it to be. Loss of VR might explain this. If that is not the case, then I think I need to strengthen my arm and wrist a lot more.

I have the D810, D750 and D7100. On each I have used the Custom Controls to deactivate the shutter release's activation of focus. I have several Nikon lenses that have VR.
If I understand your comment the VR is no longer activated in any of them - is this correct?

I read on one of the threads that image stabilization is initiated only when the shutter is pushed half way and not when the back button focus is pushed and focus is set. Is this correct?
On my D5100 with the 70-300 VRII, it stabilizes when you back button focus, not when you press the shutter.

Agree, these gentlemen are always willing to help others with their knowledge. I hold their opinions in high regard. And, enjoy their humorous side.

Canon 60D that OP is asking about should start focus and stabilization (and metering, for that matter) when the back button is pressed. Every Canon model I've ever used does this.
When BBF is set up on Canon models, the only difference is that AF isn't started or operated with the half-press of the shutter release button. Everything else operates with either half press of the shutter release or press of the AF-On (or other, assigned) back button.
I've used BBF on Canon film SLRs (mostly EOS-3, 1V, Elan 7, A2E) and DSLRs (mostly 10D, 30D, 50D, 7D, 5DII).
The older Canon models didn't have an AF-On button, so you had to assign BBF to the * (AE-Lock) button instead. That meant making a choice to either have AE-Lock operate all the time or not at all (latter is what I'd recommend, since you often don't want AE-Lock... plus it's easy enough to simply shift the camera into M mode, which acts just like AE-Lock).
Beginning with the 40D, Canon models have AF-On button (however, if using a 40D or 50D with a BG-E2 grip, still had to use the * button for BBF, because the grip that was carried over from 20D and 30D didn't have an AF-On button).
I don't use them, so have no idea how it works on the Nikon models others are discussing in this thread. It sounds like it's different than Canon.

My D600 appears to activate VR with either BBF or half press of the shutter release button. Full disclosure: I finished my last cup of coffee an hour before the test was done. ;)

I use BBF on my Canon 60D and it activates IS exactly like the shutter button.

Yes it is correct. To test this, pay attention to how much an image in your viewfinder is moving, then press Back Button Focus. You will not see any difference while pressing it or not. Now half press the shutter release button and you will see the image will settle down with far less movement.

NOT if you use stabilized lenses!!! ;-) ;-)
I have a Nikon D7100 and have tried to follow various sources of guidance on how to set the camera up for back button focus and image stabilization. Can anyone out there walk me through the steps? The manual is silent on the subject.

Not sure about all cameras & models, but I was told by Nikon that for the D7100 with BBF activated, pressing the back button to focus activates VR, which remains active as long as you hold the button and for about a second after you release the button. Meanwhile, the shutter button won't activate focus but will still activate VR with a half-press and maintain it while pressed and for about a second after release.
Do you know if this is true for the D7000 too?
