[QUOTE="WayneF, post: 368030, member: 12496"] No, not the same mechanism for VR (in the lens body) and AF-C (in the viewfinder focus system). VR does not focus (does not rack the lens in and out), but instead just moves a central lens element laterally to keep subject centered (stable position). If the shutter speed is sufficient to freeze any camera shake, it seems at best a moot point if VR is on, and at worst, it could only hurt if it did something. Nikon lens manuals all say to turn VR off if on a tripod (not needed then... and seems not needed with a fast shutter speed.) A tripod could imply a slow shutter speed, but they say turn VR off. But if you are going to hand hold 1/10 second, I'd say turn it on. :) And viewfinder AF-C is phase detect focus... instead of seeking to hunt a better focus (like Live View does), the viewfinder phase shift can already know which way to go, and how far, and it simply just goes there, a jump. That would seem an improvement if it did do anything. But... it can't. AF-C is different in Live View (mirror is up, shutting out viewfinder mechanism). It is called AF-F in Live View, and instead of focusing at half press, it always focuses, but says it locks when shutter is released. Viewfinder AF-C says it focuses continuously at half press, but does not mention during shutter release. But during shutter release, the mirror is up, and the viewfinder focus mechanism is shut out.
