Re: Yes, you can turn it off

I like the factoid that you can take multi-minute images with the D300, and my working habit includes this very important item: When shooting long exposures, lock the focus and turn off the VR. In fact, any time the camera goes onto a tripod--turn off the VR.

Of course, with the camera in the dark, how do you focus? Once, with the lights on, or using a distant detail as a focus target for infinity night shots, or manually with a magnifying right angle finder or similar aid. Then lock that focus. Leaving it live will only invite trouble.

What the value item of this whole thread turned out to be is: To clear the lens of any and all IR contamination via the VR system, switching both camera options off is the big tip.

Thanks for the research.
