I think it would help if camera and lens manufacturers would provide more detailed recommendations. They generally do seem to recommend turning off stabilization when using a tripod, but they don't bother to say why. So the photographer is left wondering things such as:

1. What if I use a tripod but it is a particularly windy day?
2. What about when using a monopod or other support such as a tree or perhaps a car door while the engine is running?

Generally, it would be helpful in general to have some answers to the "why" question.

George, I found this quote online for a Canon, not sure which model though...

“The IS mechanism operates by correcting shake. When there is no shake, or when the level of shake is below the threshold of the system’s detection capability, use of the IS feature may actually *add* unwanted blur to the photograph, therefore you should shut it off in this situation. Remember that the IS lens group is normally locked into place. When the IS function is active, the IS lens group is unlocked so it can be moved by the electromagnetic coil surrounding the elements. When there’s not enough motion for the IS system to detect, the result can sometimes be a sort of electronic ‘feedback loop,’ somewhat analogous to the ringing noise of an audio feedback loop we’re all familiar with. As a result, the IS lens group might move while the lens is on a tripod, unless the IS function is switched off and the IS lens group is locked into place.”

Cheers...

Dear Blaster-34 ...

I am a Canon user and currently own the EOS R5... I too, have continued to struggle with the same question

Being the 'Geek' that I am, I decided to perform my own 'ad-hoc' test by doing the following...

1- Set my camera w/ my RF 100-500mm @ 500. setup in my residence office, point across the street
2- Tripod was a Mammer-Jammer $ 1,200/ Gitzo, carbon fiber, w/ a $ 350 Gembal head..
3- Set my shutter speed to 1/10 second, and using the display monitor on the back of the camera
4- I then 'focused' on an 'element' across the street @ 500mm and set AutoFocus 'Off'
5- At this point, I used the 'zoom' function of the camera to 'zoom' in 16x, to test this at extremes.

..... Yes, the above is effectively 8,000mm (500x16) but, after all, you want to see the results

With the above, after taking all 'hands-off' the equipment... one can see "NO movement" of the image.
..BUT, if you 'switch' "IS" on, and take 'hands-off' ... you will see distinct 'Image Drift' in the camera display

. Just saying... and that is only "MY TEST" for my purpose and consideration...
..The above are 'real life facts' and not just some 'theory' or 'guess' or unverified 3rd party information ???
...I do most of my work in landscapes... and after all, what can it hurt to turn off 'IS" if you are on a tripod??

As a result of the above, I have made the personal decision that when I use a tripod, me personally, I will turn off the "IS" as a matter of personal choice, and a 'extra measure' to guard against 'sensor drift'

I offer the above only as info... and to each his own...
...... I am not professing that is this the right way to do things or not the right way

Just information for consideration
