I just read this in a Scott Kelby book.I wonder if this may account for some of the performance issues I have with the Fuji?
"If you want sharper sports photos, and you have lenses that use VR (Vibration Reduction on Nikons) or IS (Image Stabilization on Canons), you should turn this off. There are two important reasons why: (1) the VR (or IS) slows down the speed of the autofocus, so it can stabilize the image, and (2) since you'll be shooting at fast shutter speeds (hopefully at 1â„1000 of a second or higher), you don't get any benefit from VR (or IS), which is designed to help you in low-light, slow shutter speed situations. In fact, it works against you, because the VR (or IS) system is searching for vibration and that can cause slight movement. Normally, that wouldn't be a problem, because you want VR (or IS) to do its thing in low light, but in brighter light (and faster shutter speeds), this movement can make things less sharp than they could be, so make sure you turn VR (or IS) off."
I'd never really thought about this before but it does make sense.
It really does call into question the need for VR except in low light conditions.
