VR and IS Shutter Speeds.

Does VR and IS work at all shutter speeds? (Where it's fitted to a lens.)

Yes.
More exactly - it is working, but at a fast shutter speed (1/4000 for example) you would be hard pressed to tell the difference between VR/IS on or VR/IS off.

One advantage of lens based IS/VR is, with shutter button half pressed the viewfinder image is stabilised.

I read on the Nikon site some time ago Nikon said with a focal length up to 300mm and a shutter speed of over 1/500, the only benefit is in the viewfinder.

I would have said yes but something i read in the forums suggested otherwise. That is only kicks in at slower speeds????????

That surprised me also and lead me to question my understanding of VS.

According to Thom Hogan the reference to shutter speed is correct, the VR mechanism is apparently not reliable (too slow?) at speeds above 1/500.
Not sure about the focal length issue , though.

From memory it has something to do with the sample rates, up to 300mm it's always 1000Hz.

Above 300mm the sample frequency varies depending on the lens, something to do with the mass of the VR group and the speed it can be altered/moved.

I'm on the verge of a nervous breakdown trying to find the original Nikon listing, can't remember if was US, UK, Euro or Japan.

It stuck in my mind as at the time I was using Canon CPS registered, the only tech info from them was if it's switched on it's on.

If I find the article I'll post a link.

I think that may have been me in another post. I posted a very unclear comment that I have now tried to explain better (I think!) in the original post.
