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...

Thanks for posting this, as I knew I had read it at some point, probably back when I was still using Canons.

Only 384 pages? Many of them are now over 1100. The Canon dSLRs we used where I worked in 2010 had 500+ page manuals.

The Canon EF 300mm F2.8L IS lens will drift around with the stabilizer turned on and does not sense the tripod.

Update to any of Canon's vII / vIII IS implementations and this ancient issue is resolved.
Very good comment. I wish more commentors would quote facts instead of just pulling something out of their ___ and commenting.

====================================
Tks for your kind words Toby...
FYI: in my career, I worked in an industry where I had to be able to 'back up' what I said or did...
.... So, I learned a new phrase which was: "Show me something I can point to... "
I was in the business of putting people in jail or taking things away from them, and I had to be able to 'justify' what I did, in a manner other than just say...... "Because I said so"...
In the above philosophy, when I said or did something that 'impacted' other individuals, (employees included because I was a supervisor) it was a must for me to be able to point to a law, an employee directive, or and letter of guidance from our boss which gave us the very 'elements' which we need to consider when making out decisions...
In my post, I outline what did work for me... other things may work for others with different brands...
........... AND, that is "OK"...
So.. As Sgt Joe Friday would say -- "Just give me the facts mam' " ha ha
Cheers and thanks

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
Cheers

I use a Sigma 150-600 mm a lot and when on a tripod I need to switch the IS off otherwise the images will drift. I have just got into the habit of turning IS off when shooting on a tripod, no matter what lens I am using. It is not a big deal to turn it off when on the tripod and back on when I an no longer on the tripod.

I always shoot with stabilization “on” with my various cameras, and I have had zero issues while shooting with a tripod. Perhaps many years ago that may have been a problem, but not with my cameras, and they aren’t particularly “new”!
No it still is happening with some cameras and lens combinations. I have both a Canon "R" and also a R50 as well as a older dSLR 70D it and it happens on all of the cameras with certain lenses.
Be glad your camera, make and model is one that works with the stabilization turned on.

It is better then not having a manual at all!!!! Still seems far to many won't even glance at one when they have it.

Tri-pod or not 15/sec lock up mirror, basic skill.
