A few things to note: The original thread here is 14 years old :). All bets are off in high winds. Actually, some panes are from 2008! More than 16 years ago. The technology today is far improved. That said, I leave OSS on when on a tripod whether for flight or for static. Mode 2 is on all the time. In addition, the camera can make a difference as well as with the Sony a-11 ii.

One of the big changes in all those years is the way optical IS works on RF lenses. In EF the IS elements were locked when IS is switched off or the lens is off. In the RF the optical IS is floating, so needs power to lock it in place when IS is switched off. So uses power, albeit a tiny amount, even when IS is not active. It also rattles quite a bit when the lens is detached or the camera is powered off. I’ve seen quite a few panic about that.
 
The issue of having image stabilization on or off is lens specific. With my Nikon lenses the "VR" off on a tripod varies with each new generation of optical stabilization. The better lenses can sense movement and stabilize on the vertical axis and ignore movement along the horizonal axis.

The user needs to take the time to read the manual for the lens that is provided by the lens manufacturer and can be downloaded as a PDF file. I do this every new lens I acquire.
 
hello everyone how are you, we wish you a new year full of goodness and blessings.
I agree with you. It happened to me when I turned on the image stabilizer in tripod mode, and when focusing, the focus point jumped and the images were distorted, and when I turned off the image stabilizer, the focus was normal.
It depends on your lens per Canon. Check the manual for your lens.

Canon's Image Stabilization (IS) lenses often feature Tripod Detection, a function that automatically disables IS when the camera is mounted on a tripod to prevent unnecessary movement correction. Many L-series telephoto and super-telephoto lenses include this feature.

Canon Lenses with Tripod Detection (Examples)

  1. Super-Telephoto Lenses
    • Canon EF 300mm f/2.8L IS II USM
    • Canon EF 400mm f/2.8L IS III USM
    • Canon EF 500mm f/4L IS II USM
    • Canon EF 600mm f/4L IS III USM
    • Canon EF 800mm f/5.6L IS USM
  2. Telephoto Zoom Lenses
    • Canon EF 70-200mm f/2.8L IS III USM
    • Canon RF 70-200mm f/2.8L IS USM
  3. Other High-End Lenses
    • Canon RF 100-500mm f/4.5-7.1L IS USM
    • Canon EF 200-400mm f/4L IS USM Extender 1.4x
These lenses include an advanced IS system that automatically detects when the camera is stabilized on a tripod and adjusts IS operation accordingly.
