I followed the link provided above and read the Nikon white-paper on VR and it doesn't appear to say anything one way or another about BBF and VR. Unless I overlooked something, it only describes VR function when using the camera without BBF set up.

It does note that there are "Normal" and "Active" modes (at least with some lenses.. I don't know which or how many or if that's with all Nikon cameras) that can be selected whether or not you want full time VR to help stabilize the viewfinder image such as when tracking moving subject (Active), or if you only want VR to acknowledge and respond to camera shake/movement right at the instant of exposure (Normal). Canon IS doesn't commonly offer this choice, per se, however some more recent IS lenses have a "Mode 2" which is an "instant IS" only at the moment of exposure... in addition to "Mode 1", which is used for panning shots where only the vertical axis is stabilized so that IS isn't counteracting deliberate background movement blur... and "Mode 0" which is normal stabilization on both vertical axis and horizontal axis, full time, including stabilization of the viewfinder image.

I also found it interesting that that web page actually talks about using VR on a tripod to correct for the fine, internal vibrations of the camera, even in the absence of other more dramatic camera shake. Most users here and elsewhere seem to feel VR should always be turned off on a tripod... but Nikon seems to suggest just the opposite. (It's similar with Canon... with most IS lenses there is no need real to turn it off on a tripod, it cancels itself in the absence of any movement... only a fairly short list of older and simpler Canon IS lenses "freak out" on a tripod and require it be manually turned off. Despite this, Canon recommends turning off IS when using a tripod in most of their lens instruction manuals, but really only to save a little battery power that it consumes when working, according to Canon's tech guru Chuck Westfall. In my experience using various IS lenses for 15 years, it really doesn't use much power so I almost never turn it off.)
