Do I have to turn off stabilizaton when using slider? Why?

If the camera is only translating ... then stabilization shouldn't affect the shot.

But if the camera is rotating (pitch, yaw or roll motion) then if the stabilization system is turned on it will try to "fight" the movement.

I am confused by your explanation.

The TLDR is that sliders alone only perform translation and the IS system shouldn't try to do anything and therefore you shouldn't need to turn it off. But it's probably easier to just turn it off whenever you're using something like a slider or a gimbal so that you don't get them mixed up.

The longer explanation:

I stole these images from: BlueGrowth.org. They illustrate a ship, but the same motions can apply to anything.

"Sway", "Surge" and "Heave" are specifically nautical terms, for example "heave" describes the motion of an elevator.

Notice the difference between the two sets of motions (which together comprise the six degrees of freedom). For example, Heave (a translation) differs from Pitch (a rotation) because when a ship heaves the entire ship moves vertically - the bow and stern go up and down together. When the ship pitches, the bow is going up while the stern goes down, or vice versa.

Can you clarify for me any of the following would require turning the stabilization off?

1. Pan/Tilt with camera on tripod.

Pan and Tilt are rotations, they correspond to Yaw and Pitch in the diagram above. IS would attempt to compensate for these motions.

2. Pan with camera on gimbal, with my body rotating, not the gimbal's handle.

3. Tilt with camer on gimbal, with the camera pitches about 40 degree.

If the camera direction is changing, then the IS system will attempt to compensate. It doesn't matter whether it's handheld or commanded on a gimbal - a pan is a pan and a tilt is a tile. See (1) above.

4. Up/Down movement with camera on gimbal. The camera is locking on distant subject.

5. Left and right on slider.

These are translations - the direction that the camera is pointing does not change. up/down corresponds to Heave and left/right corresponds to Sway in the diagrams above. Because the direction is not changing, the IS system will not try to compensate.

With one exception, I actually have seen any problems with all my movements.

I do find some jittering when I pan (mostly on gimbal). I don't know if I had moved too fast or was it the IBIS issue.

I will pay attention more in the future.
