[QUOTE="BackdoorArts, post: 444625, member: 9240"] Just so I say it, I'm not going to get into the pissing match that inevitably happens when someone tells you you're wrong - but suffice it to say you're absolutely wrong here. Half-pressing the shutter button (or engaging BBF) physically engages the VR mechanism on the [B][I]lens[/I][/B], which translates to a stabilizing effect in the viewfinder. Heck, with my Sigma lenses you can actually hear and feel it. That mechanism continues to respond through the depression of the shutter. Releasing the button(s) turns the VR off, though some mechanisms continue to spin for up to 1 second (my Sigma 150-500). VR continues to operate during the entire process, but it does not turn off and re-engage as you state, and yes there may be additional compensations that occur during shutter engagement, but viewfinder-only stabilization is a function of many mirrorless and P&S camera[I]s [/I]and is usually done via sensor algorithms and not via an internal gyroscope.
