"Here's where the dilemma comes into play: a number of Z-mount lenses don't allow Mechanical (M). If you were previously set to EFCS, all you see is the grayed out E and you might think that you're in some kind of "all electronic" shutter mode (you're not, you're in EFCS). All three DX lenses lock you out of changing Shutter Type to Mechanical. The upcoming 100-400mm lens does it, too. Indeed, many of the lenses with built-in VR do this. I believe the reason for this has to do with the timing interaction of the VR mechanism and the image sensor. But in no case is this "all electronic" as some people are complaining. Again, there is the limitation of 1/2000 shutter speed to worry about, though, if you set EFCS."

Yet the 1/2000 s limitation only kicks in if you actively choose EFCS. If the camera reverts to AUTO, then I would assume that it would revert to mechanical shutter for shutter speeds not suitable for EFCS, probably 1/2000 s and faster. For these shutter speeds, it would appear likely that any problems resulting from the interaction of the VR and the mechanical shutter are no longer present (either the mechanical shutter does not affect VR anymore, or the effect is insignificant at these shutter speeds, or VR is disabled altogether at these shutter speeds).
