I am wondering if this could be the cause of my concerns over sharpness as per my earlier thread?

I'll be doing VR on/VR off comparison shots for a while to see if it is causing my blur.

yeah when I read that today, it really got me thinking. . .I have noticed a SUBTLE difference in bokeh when on and off on the 70-200 vr2. . .

I usually keep it on active all the time, since I'm moving around a lot during events. . .but I guess if I was doing landscape, I'd probably turn it off. . .

His explanation about how real pro's keep it off, and you'll rarely see a pro on the sidelines at a football game with their 400 2.8 VR switch ON, really got me wondering if that was even remotely true (unless on a monopod). . .

Borrow Lenses just posted a link by Thom Hogan to this very good piece on Nikon's VR.

The first and most important rule of VR is this: never turn VR on unless it's actually needed.

Yes, this rule flies in the face of what most everyone in the world seems to do and what the camera companies imply with their advertising and marketing. The simple fact is that VR is a solution to a problem, and if you don't have that problem using VR can become a problem of its own...
