I just read this in a Scott Kelby book.
"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.
Haven't got VR on any of my pro lenses, but confess that the collection of lenses I acquired for the D7000 all have it...always on. Maybe I am less discerning these days, but the out of focus shots I see are down to me technique and not any hesitation that VR might be applying.
I suppose if you are trying to suck out every grain of quality it's worth considering every bit of help.
