I have tested all shutter speeds. Of course jittering shows less with very long shutter speeds or with blurred background like 24P judder. MEGA OIS lenses has no jitter at any speed. Focusing distance may affect too, I think there is less jitter with close up shots than at long distance. Best way to avoid jitter is to keep the camera in motion all the time. Very slow pan or movement hides jitter.

@Vesku: I fully confirm your findings. I owned many Panasonic bodies and lenses. The Vimeo and Youtube examples referred in this topic are showing the typical behaviour.

Mega OIS lenses do not seem to be affected.
Many Power OIS lenses seem to be affected. I tested 12-35 (minor jitter, especially at 35mm), 35-100 (very bad, very stong jitter), 14-140II (more jitter than 12-35, visible at all focal lengths).
Issue seems to be independent from body (I tested GM1, GX7, GH1, GH2, GH3, GH4).

AFAIK, Panasonic never confirmed this issue. I have to use NLE stabilizers to make handheld shots usable.

Some more findings I forgot to mention:

35-100 has the best Power OIS for photos. It is the only telephoto zoom which avoids Shutter Shock on bodies without Electronic Shutter like GH1 and GH2. This lens seems to be optimized for photos.
The tiny PZ 14-42 has a Power OIS as well, but does NOT Show any jitter. I really like this lens.
The PZ 45-175 shows minor jitter as well. Comparable with 14-140II.

On the other hand, the tiny 12-32 lens has a Mega OIS, but nevertheless shows some minor jitter.

I wonder why Panasonic continues denying this issue. It is clearly proven by many video samples.

I'm talking about the tiny 12-32/3.5-5.6 lens here, which is part of the GM1 kit.

I think we must send our lenses to Panasonic service. Maybe then they will take that issue seriously. If they find nothing faulty I guess we must pay some checking payment and posting. Has anybody sent a POWER OIS lens to service due to jittering?

By the way a new version of Mercalli is coming. Maybe it has good features to fix jittering. I have tested current version (demo) and it removes OIS jittering with very little cropping. The batch processing still crops too much.

I had the chance to test a 12-32mm Panny zoom (Mega OIS), a 45-150mm (Mega too) and a 12-35mm Power OIS close to each other. I can confirm that they behave differently, but none is perfect.

The Mega OIS zooms didn't exhibit the micro-jitters, but instead they show some jumpiness on movements, like panning. It looks as if they stick for a moment and then catch up.

The Power OIS in the 12-35mm after the firmware update is far better than the one in the 35-100mm, but it shows some residual micro-jitters.

Since the 12-32mm has no manual controls whatsoever, I'd rather go for the 12-35mm. The 45-150mm OTOH is working quite well if you only want to keep a handheld (actually, shoulder) shot quiet without any movement – and any panning at such lengths I'd rather do from a tripod anyway. Yes, it's slow, but it's sharp from open aperture and the bokeh is not bad.

I made again some heavy testing today with my problem lens Pana 14-140 II. I shooted with a short monopod. I attached a heavy weight to monopods lower end and used it leaning to my body (not ground). Image looked very stable in EVF and I made some very slow and perfect pans and moves. When I came home and watched clips the same jittering was there. The OIS is so sensitive that any minor vibration makes it jitter. A good tripod or post stabilization is the only way to get decent shots.

My trusty G Vario 14-45 f3.5-5.6 is fine for outside shooting. Focus is quick and relatively quiet. A real workhorse, and not too expensive. I'm wondering if the jitter problem is more pronounced with the long barrel zooms.

@sportster I did extensive "shutter shock" testing with these lenses (and a few others). My testing results indicated that only the 14-140mm mk2 lens had obvious "shutter shock" problem. Unfortunately, the problem is pretty bad with the 14-140mm mk2 lens resulting in pronounced image degradation. As a result of the problem, I have configured one of my Function buttons as a switch for the Electronic Shutter. The Electronic Shutter masks the issue, but has its own drawbacks.

Back to movies...

Yes, I agree that to my eye the Power OIS performance of the 35-100mm f2.8 lens exhibited the most severe "micro jitter" of the lenses in my tests, followed by the 14-140mm mk2. The 42.5mm also showed some "micro jitter," but not nearly as much as either the 35-100mm or 14-140mm mk2. To my eye the 12-35mm f2.8 lens had the least "micro jitter" of all the Power OIS lenses I tested. In my opinion, not a problem at all and roughly equivalent to the MEGA OIS of the 100-300mm lens (with allowance for difference in focal length).

I also tested various stabilization products (SmoothCam and Lock and Load X) and they are both effective at eliminating the "micro-jitter" symptom with only a very small loss of framing. I think less than 1% crop would be enough to eliminate "micro-jitter" effect. Not terrible considering I needed up to 5% crop to eliminate the residual hand-held motion in this test footage (I'm an old, unstable bastard). Practically speaking, if you typically use a software stabilization product like these, then "micro-jitter" is probably not much of an issue. On the other hand, if you are a lazy, old, unstable bastard like me and just pop the card out of your camera and play unedited hand-held footage on your (U)HDTV, then the performance of Power OIS + hand-held movies is annoying at best.

FWIW - Some months ago I did test Power OIS when the camera was attached to a tripod and did not detect any "micro jitter" with Power OIS on. Before the v1.2 firmware upgrade, my 12-35mm f2.8 lens did exhibit "micro jitter" with Power OIS off.

When I get more time I'll probably test how these lenses and Power OIS performs when the camera is attached to a monopod.

@Vesku I agree to your findings.

Are you talking about the 14-42mm 3.5-5.6 II lens? I don't own this lens, but I have the tiny PZ 14-42 3.5-5.6, which is rock steady as well. (BTW, although labelled with POWER OIS).

Another fine lens without micro jitters is my trusty 45/2.8 Macro with MEGA OIS.

The 14-42mm V2 works quite well - I´m using it since many months on a GH2 and a GM1.
Dirt cheap, very lightweight and delivers very good IQ (also fit´s the GM1 perfectly) - Fully recommended ^^.
