70-300vr - Any shot over 1/500th (FX) (1/750th - DX) is sharper with the VR turned off. When on a tripod where there is no movement turn off, but if there is some movement leave on.
105vr - Any shot over 1/500th (FX & DX) is sharper with the VR turned off. Always turned off on a tripod where there is no movement as any time I leave it on the shot is not as sharp. Shakey tripod (or i'm holding the camera while on a tripod) I find it sharper with the VR on.
24-120VR (ver 1) - never seen any difference at any speed or tripod - (lens isn't that super sharp in any regard.)
I have used many others, but don't own any of them now or ever did much testing with them. I just followed what...next Line
2nd Rule - Each Nikon VR lens clearly states in the manual how it is designed to be used for and when (and what setting) it is to be used for. Read the Manual!
The Nyquest frequency is 1/500th. It states (paraphrasing) that at or above 1/500 the shutter is so fast that shake can not exist. In practice I know that is not true - but does hold true at or above 1/1000th.
I have read on Nikon's site that most VR lenses, VR should be turned off when on a tripod. That said, I know that on the big lenses the VR is designed to but used on a tripod. The 300mm MANSUROV tested might be the cut-off where that on down VR should be turned off and the 400 on up should be left on. Maybe if MsMoto jumps on she can take a look at the 400mm manual to see what it says.
What MANSUROV's results were seems in line what I see with my 70-300vr informal tests. It would be interesting to see the 105vr tested in this way. I'm not sure if I have seen a real difference. I do see a real difference more at the above 1/500th shutter speed with the VR on - the images are considerably less sharp and the VR does actually introduce "camera shake" looking results.
The VR on the new 80-400 is amazing
The 1/500 came from Thom Hogan's Rule #1 and Rule #2 below:
Thom was making an educated guess about the limitations of Nikon VR pre-2010 (when the article was written). Since Nikon VR operated at a sampling rate of 1000 Hz, he proposed that VR was not effective above 1/500 (half rate, due to Nyquist). This is not the speed where "shake can not exist", but a limitation of the 1000 Hz Nikon VR implementation at the time.
Also, read Thom Hogan's Rule #8 about reading the manual.
Just keep pounding this stuff into my head people. I'm slow, but I just might (eventually) pick it up.
At higher shutter speeds, 1/800 and up I turn it off or sometimes forget to do this. I have not seen any particular loss of sharpness, however.
I had an NBA photographer tell me the best thing to do with VR is to get some duct tape and tape over the VR switch so you can't accidentally turn it on.
I'm sure it work greats in some venues, just not the ones I shoot. I will say my 2.8 lenes does a little better with VR but not as good as not using it. I've tried the whole gamet with it and have found the duck tape works the best for me.
But the ranking stays the same:
Fast shutter speeds or solid tripod
Handheld without any anti shake measurement.
As I was saying on another post, my 70-200/4 I can handhold down to 1/15 with still usable results (I know the difference between usable and tack sharp ). While my colleague's 70-200/2.8 VR II used by me was not as good at the same shutter speed. But I was not used to it. Somebody who developed a good posture with this heavy lens or has different body proportions will get different results.
These are a variety of lenses and some don't have VR, but still
On with tripod
I just think there are so many factors that it should be hard for one to judge it being the VR. And it has saved me far more then I can tell hurt me. Leaving it on hasn't ever ruined a picture, but not having it on has. And what is the real rule for VR? Is VR really making my picture less sharp if I keep it on at fast shutter speeds? It shouldn't really make a difference should it? And at slow shutter speeds it can only help. Even with a tripod I haven't ever been disappointed by it. If anything my focus being off is my main reason for unsharp pictures. I could be blind in one eye and have glaucoma in the other though (sorry inside joke).
I know some have mentioned shutter speeds. If the shutter speed is high...then VR should be negated as it isn't reacting fast enough to make a difference. On the other hand at slow shutter speeds it can only help. So is there somewhere between that isn't optimal? I can possibly see the tripod thing and it trying to engage VR when it isn't shaking, but I really have never encountered this either and wonder if someone actually has.
And not to mean you can't take sharp pictures without it on. Now with my 300 F4 I don't have a choice and it takes sharp pictures.
I tend to turn off VR when I'm my shutter speed is 1.3x over the focal length. Depending on the situation and how I shoot (A & M mostly and 50% with auto ISO and 50% without,) my shutter speed may roll up and down as I zoom in and out to the point my shutter will go to 1/50 when I zoom out to 200mm (70-200vr) so I leave it on. I can say with that lens the VR helps get more shots than I miss. Now if I'm over 1/400th and I know my ISO will not go above 500, I just turn the VR off. The little wildlife stuff I shoot I can tell that VR at fast shutter speeds invoke "Phantom shake" into the image.
With my 105vr at macro shooting, I really can tell that the VR creates "Phantom shake" in images where my shutter is over the focal length. On portraits though, not so much. Much of that has to do with how much detail is captured and the D800 is unforgiving at 400% zoom.
Nikon has written about all of this extensively - this was just a quick search on their site and what i found.
Micro-Site all about VR
@TaoTeJared ....... Thanks for that info. I'm an old man as you know so my hand shakes quite a bit after shooting for a while. Once that happens I crank up the speed I'm shooting at. What you said about the ISO may be my problem. I always try to keep my ISO as close to 100 as I can. Maybe less aperture and a higher ISO will allow me to use the VR affectedly.
