The VR has the inner-workings of the lens "floating" on a gyroscope. You'd probably have to turn the VR off to shoot good images underwater even.Fota:Doesn't VR come in handy when shooting uw without a strobe too?
That may not be the most common case with the 105, but with a wide angle lens, and even normal lens, I can think of many situations where I would like to shoot with no lens. Also, if shooting in more shallow water (lets say <= 10m) with the magic filters even with 105, the VR would come very much in handy. Well at least that's what I thought?

We need someone who has tried the VR underwater to know for sure...
My friend (store below mine) sells Nikons, and he tried the Nikon VR 18-200 vs. a Tamron 18-200 and both images lens for lens - same shot - hand held - the nikon vr lens had softer edges than the tamron. His recommendation (he shoots scenic photography professionally and has supported himself from his gallery for years) to clients in his retail shop is to not go towards the VR lenses, and that most pros that he speaks to don't use the VR lenses either.
