I have always followed the advice of turning off the VR when using a tripod. Why is this the correct way to use VR? Can anyone tell me what will happen if I do not turn it off while using the tripod? I tried it on and off using good old "scientific method" of testing and I do not see any difference.
I don't see any difference either when I'm using a tripod. I own only one IS lens (Canon) and when using that lens I never turn the IS off. Of course I do lots of video with that lens and the IS gives me a steady cam look. But no difference on or off a tripod.

I know the manufacturers must understand their equipment since they made it, but think about it, they probably don't use it in the real world like we do. The consumer is often the beta tester in the mad rush to market with new technology. The assumption that all the info is complete and understandable in the manuals, belies the fact that there is always a seemingly endless supply of third party books to substitute for said manuals. That alone says something.

Probably because they don't really know. Lots of products are created, sent to market and sold, and in wide use before problems are identified and resolved or unintended consequences are realized.
Once, I cracked open a fortune cookie....., and by golly....., it said exactly what you just said!!!
I'M a believer!!!!!

All of the techs shoot the brands that they tech.
And no, you are NOT the beta tester. They use real world pros like at the Olympics or Art Wolfe and such.
I'm sure computer simulation programs find most of the bugs, then updates to the processor can fix a lot with software.
Know your gear. Read the manual. Call and talk to tech.
I'll admit, the average guy knows as much of their camera as they know about their car, which is zipp0.

People keep banging on about VR and a tripod. It does not matter if the camera is mounted on a tripod or on a brick wall; VR kicks in when motion is sensed within the parameters that the system is designed for. A tripod need not necessarily be motion free; wind vibration is a major potential problem, VR would counteract that if the camera's VR parameters are in range.
The effect of leaving VR on when there is no motion detected causes the VR mechanism to look for motion; not finding any it does not react to it. This may take a few nano seconds to run; personally I have never noticed. There is talk about VR introducing motion blur when the camera is clamped rigid; personally I have never experienced this and neither has anyone else I know.
The correct way to use VR is when you are shooting below the threshold that the VR works it should be on; if you are shooting above that threshold, you can switch it off. So a 400mm lens requires a 1/400th exposure time to avoid potential motion blur; at 1/100th VR should be used, at 1/500th it should not.
However most - all - people seem to leave it on all the time without complaining about it except when it does not work as they think it should.... but the presence or absence of a tripod, bean bag or convenient brick wall have little to do with it.

I'll give you a real world example of a mistake I made with VR. Draw your own conclusions. I shot an entire evening of the Detroit fireworks from across the river in Windsor, Ontario, Canada on a tripod with the VR on during 10 second exposures. The result when I got home and looked at them on the computer was pea soup mush.

It depends on the lens. Read your lens manual. If you can't find your copy, you can download a copy from "support" on the manufacturer's web site.

Just talked to a friend who just bought a Canon 7D Mark IV (I think), and he said the manual was 667 pages in length, had small type and was of course translated from the Japanese.

There are so many different systems out there it is increasingly hard to remember how they all perform, even within an OEM brand. I have several Nikon lenses with VR, of various versions, and I'm just too old to keep track. I turn it off on a tripod & monopod, whenever I'm above 1/focal length, and on when handheld. Seems to work for me. I do have at least one newer lens that says that it can be left on on a monopod, but it does not demand that you do. As a shooter from those older days of film, manual focus and film advance, I never had the option of VR anyway. I must say I like it on my Nikon 300 F4 PF!
