In this case, since the vignette is visible, the OIS shifts this around.

I've heard of no complaints with vignetting at full wide and max aperture f1.9
The vignetting issue mainly affects 8-25mm range with aperture settings wider than f5.6.
This is known issue that affect some (apparently quite a few) of these cameras.
My replacement camera also has the issue, although, not as bad as my first.
Cameras that have this issue can watch the vignette shift around with OIS on.

Paul, your camera is probaly VERY close to my current camera.
I'm not sure why Sony is claiming your camera is OK, when we all know there are cameras that do not have this issue at all.

I'd like to know the specfics on how they are making this adjustment.

Oh. I understood his post to mean that he saw no vignette until he moved the camera.

I've contacted one of the managers at Sony UK who I met through the video forum in London to find out what he thinks about it. I'll hold out from getting too rattled about it until I've had a chance to talk it through with him first.

My camera only suffers very very slightly with OIS off, and I'm happy with those shots. But I've started using my shoulder rig a lot lately and like to use OIS. If I handle the camera very gently I can get away with it, but any sudden movement brings the darkened corners crashing into the shot.

Watch this space!

Paul,
OIS is usually recommended to be turned off on most cameras when the operator is panning/tilting while on a tripod or movement via steadicam, dolly, etc., due to the OIS fighting the intended movement of the camera operator - which I don't see as as being any different from being rigged on your shoulder unless you are being completely static.

But a problem is a problem and I'd put it back on Sony to fix it.

Just two cents worth - good luck,
Lonnie

Pretty much correct, I can see it with OIS off, but it's so slight that it's not a big problem. With OIS on though, the fact that the effect has motion makes it much more apparent.

Look at this clip, http://www.olikai.com/shake.mov it's a very wobbly shot, way too wobbly to use but you can see the effect on the right side of the frame as the camera wobbles.

Paul, I'd like to see this same test with the OIS off. Mainly between 8-25mm.
When you say slight, I'm wondering if mine's worse.

The first frame of that clip is a pretty good indication off how it looks with OIS off as the stabiliser isn't having any effect at that point. All you can see is some slight graduation in the top right corner.

Paul,
my apologies...
Here I am chiming in about reducing intentional operator movement with the OIS activated, blah blah blah and then I saw ois-vignette-1.mov:

Don't short change your self, something is amiss with your camera, send it back for a new one.

Yeah, that's pretty awful. I wouldn't accept that either...

Those of you who sent in their cameras - how long did it take to have it repaired? My camera is away for a week now and Ive not heard anything about it yet. Ive sold all my old cameras on ebay and Im now camera-less...
I called Sony Service today and they did not know anything about the EX1s status. They did not even know where exactly my camera is! They only know that it arrived last week. I have to say that Im getting a little impatient now.

thanks and regards,
Gerald

Did the test today and I find I have some vignetting. Really very slight in top right corner. Mine was bought late but was an early model so should I insist on an exchange from B&H or just let SONY rebuild it? Have there been any modifications made that make it better to try for a current camera?
