Based on what I've read, the D7000 starts VR by pressing the shutter release button, regardless of whether you've mapped AF-ON to the back button. Correct?
If so, is there any practical downside to this? For example, is there a chance that since focus has already been acquired via the back button, that somehow VR won't acquire in time for the faster response? Or does VR acquisition complete no matter what, potentially negating any faster response? What about the VR stabilized display in the viewfinder as well?
