"The windows were "floating" around . Is it due to the Image stabilization?"

Yes, the camerastabilisation is trying to correct for the movement you make and on a tripod that is not something you want. I notice this very clearly on my Canon xh-a1 if I leave ois on when on a tripod, if I do a pan movement when zoomed in and when I stop panning the camera tries to correct after that and I see the image move, eventhough the camera is standing still.

If you don't want that "floating movement" you need to turn ois off when on a tripod.

thanks !!
 

thanks for clarifying that.

I *think* you have saved me from a major mistake this coming saturday.

I SO appreciate it.

IS is still useful in certain tripod shots though. For example, if you have a locked down shot at full telephoto, it is quite common to see some wobble in the image due to the tripod not being perfectly rigid, or maybe when the tripod is standing on a flexible surface like a wooden floor. The IS helps in these cases to reduce camera shake.

But I agree that if you need to pan the camera, the IS is usually better switched Off.

how do you assign the OIS to the custom buttons, I don't see it on the list of options ?

Can't do it on the A1.

It's an option on the A1S.
