[QUOTE="Eyelight, post: 367868, member: 24753"] In order for VR to work, it would have to be making adjustments during the entire exposure. If it corrected at a slower rate, it simply could not correct camera movement at all. What the sampling rate does imply is there would be no need to use VR above 1/1000 sec, but then again, I can't shake that fast, so I probably would not need it. I do wonder how much VR helps and does it sometimes hurt. Could explain some soft images at times. AF is driven by entirely different sensors, so I imagine there is no relation to the VR system.
