Depends,
some of the latest Sony cameras have a new stabilization system that you really want to switch off. We had one on sticks and left the stabilization On and every so often the image would jump up and down quite a few pixels. Sony's answer was the stabilizer must be off except when hand held or even someone walking past on a concrete floor could trigger it into doing twitchy things. I suspect this might be a combination of factors though, we had the camera pointed at a large brick wall at the time. Pointed elsewhere I don't recall the jumps happening.

Monopod OIS always on
tripod OIS off.. moreso with canonand Sony cams as theyre stabilisers are striggered by motion (of teh cam) as well as motion within the frame (XY analysis or some shite like that)

With a DVX, u can leave OIS on full time as the DVX has a very crap OIS in the first place so on a tripod it wont make a differnce. It specifically pics up gyration and nothing else (pans are still ok with DVX on tripod
I always say to people, if you want to learn stable handheld camera techniques, practice on a DVX. If you can make handheld look good with a DVX u can make it look good with ANY camera..

This is news to me. Everything I've shot over the past 7 years with tripod has been with the OIS left on, and I've never seen any odd motion in the 3 Sony cameras I've used (TRV8, VX2000, FX1). Same goes for my little HC3, which I've had for a year; it uses digital stabilization.

put it this way, with OIS on, if u start a pan, and depending on how smooth it it, the camera will try to compensate that panning motion by offsetting beck in the opposite direction (ie pan left, and OIS offsets to right)
Now as the OIS can only go so far, it will jerk back to the left once it reaches its Left/right threshold

I cartainly knwo the FX1 has issues with OIS on when its on a tripod, as I got a call from a Videographer who had this exact issue when panning on a tripod, had OIS on, and the pan itself went around a pillar.. that pillar jerks and threw off the OIS
They thought it was Vegas slowmotion, but it wasnt

Thats just one example..
Another would be to have OIS on and then have a largish subject move across it

I <3 my monopod! Actually posted this pic on MySpace recently but since some of ya aint on it:

i luv my 560b

With my VX2000 the OIS is always on. Hand held, Monopod, or Tripod. Never noticed a problem except when I tried turning it off when using a tripod. Maybe it's that particular camera that works better with it always on.

DJPadre:

I'll look for that effect the next time. I think I'm reasonably critical and never noticed a time when the camera OIS did something I didn't expect or want. Certainly one of the most important aspects of designing a steadying mechanism is to make sure it doesn't lock too hard on an image, because that implies it will "snap" upon release.

I'm very familiar with DeShaker and the issues involved with steadying. It's impressive how DeShaker almost always does the right thing, even when large objects move across the field of view.

How about with the Canon XH-A1?

I was using an XH-A1 on the pics I posted. I run with stabilization on with the monopod and havent had a prob.

I think it depends on your use withthe mono pod.Most shots witht the pod arent "locked down" shots. I mean you may be holding a shots still for awhile but you still are going to have some slight movement from your body. Or your shooitng shots like Mutt where your holding them cam in hte air then back down etc. it doesnt make sense to turn it on & off. on is usually fine (depending on the cam) .I can tell you this I aggree that the FX-1 has issues with pans with it on especially when the cam is on sticks and is dead motion less right before the pan. I always turn it off with on sticks, I especially need to make sure its off on sticks in the environment I shoot in mostly, on boats.
I can tell you this that the FX1's optical stabilization is not image sensed but gyro sensed. turning it on with a locked down shot on an interior of a yacht. ..when you watch it later(even in the view finder , the gro is trying to compensate for the even imperceivable motion of the boat rocking in the water. Makes even me with a sturdy set of sea legs ,feel queasy.
