HPX170 Jitter when zoomed in.

[GraphicPlanet]

I'm out on a shoot using an HVX200 and an HPX170. After transferring the footage I noticed an unusual amount of shaky jittering when zoomed in and even when not so zoomed in with the HPX170.
It's the first time I've used the HPX170. Has anyone else had this issue. An amplified amount of jitter in the shot like your hand had tremors.
This didn't appear at all on the HVX200 footage.

Thanks!

Shooting handheld with the OIS turned off ?

Dingo, you might just be my savior! I called the camera operator in the next room and OIS is off! So I guess we will find out tomorrow when we shoot. Thanks!!!
