Couple of new tests. You all with that lens should be worried.

Thanks for your example.

Your sample video is not very stable either. It vibrates somehow like mine. Does it vibrate noticeably at 14mm?.

My Pana 100-300mm lens is completely stable and not vibrating at 140mm when handheld carefully.

@ntsan

Thank you very much for your help. With your clips I can confirm that my lens OIS is not working properly. I made a comparison of 100-300mm and 14-140mm mk2 at 140mm in my vimeo page.

So I now visited my store where I bought my 14-140 II. They had those lenses but they could not open boxes so I was not able to test another copy of that lens. That is a pity but I still tested their demo piece of 12-35mm which has the same kind of POWER OIS.

The result was stunning: My 14-140 II and the 12-35 gave exactly the same jitter at 14mm. It was clearly visible at 2k. I had my old 14-42mm also and in comparison it was clearly the best. No vibration at all at 14mm handheld.

This is beginning to be very interesting. The camera experts of the store personnel were shocked by this result. At least one of them has GH4 and 12-35mm and he promised to make his own tests and report to Panasonic about this issue. There were 4 experts and each of them admit that there is an issue of Panasonic POWER OIS.

I would be very happy if the owners of Pana POWER OIS lenses could report if they can see this vibration when trying to shoot stationary video handheld. The issue is not present when shooting "amateur style" sweeping and panning and zooming nervously.

It would be very odd co-incident if those two lenses we tested would be faulty ones.

People may think that some shakiness is OK with handheld video. I say that if one shoot carefully at widest end (12-14mm) it shoud be very stable. That kind of vibration is not acceptable with even cheapest camcorders. Why should we tolerate it with high end gear that costs thousands of dollars.

@CNek

Thanks for feedback

Could you shoot a handheld video clip at 14mm trying to hold image carefully stationary. Can you see a little rapid vibration in that video clip. If the lens works properly the clip should be very stable without no jitter or vibration almost like in tripod. My 14-140 II jitters when shooting stationary at 14mm. I tested 12-35mm at store and it jitters too. My 14-42mm has not jitter. The jitter you should see is rapid 1-2 pixel random jumps in video generated by OIS system. You must watch it at close distance.

Could you report your findings.

Thanks.

I just got a notice from the official austrian support company, that panasonic is aware of that problem, and IS working on it. so there is hope that the 14-140mm MK2 will get the same fix as the 12-35mm just got

Can you clarify this? The 12-35mm lens received a firmware upgrade about 15 months ago, but it was to fix a jitter when the OIS wasn't engaged.

I'm with @Vitaliy_Kiselev - From what I've seen posted on this web site and others, I think there is a problem with Panny's Power OIS on their recent zoom lenses when taking movies hand-held. I've seen the "micro jitter" in movie footage from the 35-100mm, 12-35mm and now the 14-140mm MK2.

At least the Power OIS in 12-35mm and 35-100mm holds up well in photos. Unfortunately, the 14-140mm MK2 suffers (horribly) from "shutter shock" - so much so that I always use electronic shutter by default with that lens unless my shutter speed is faster than 1/400.

One owner of 35-100 f2.8 has reported the same issue.

@Vesku

Please keep it to the issues topic we have.

I just tried out ProDad Mercalli SAL v4.0 which not only stabilize video for motion, but can also analyze jitter/wobble caused by cmos-sensor-readout and high-frequency-motion. Until now i was not able to correct that kind of video with after fx/deshaker or anything, but Mercalli SAL v4.0 seems to do a tremendous job. It takes half an hour for just a short video, but at least it works quite good. Checkout the stabilized version of my video:

If you stabilize this video with after-fx you get a stable video with constant skew's across the frame, truly unwatchable Mercalli SAL is a little bit pricy, but so far it's the only thing that could help me with OIS Jitter

I sense the frustration ! I have the problem lens's as well, and I can't believe Panasonic released junk like this for a lot of money. I think it would be helpful to see video of a handheld lens that does not exhibit the issue. That would mean there are copies out there that work, and points to shoddy quality control or manufacturer tolerances . But I'm not surprised really.... I had a Sony 3d camcorder that had a soft focus on the left eye. The Sony repair facility emailed back and forth with me, and claimed they could not see the problem. Amazing.

Panasonic will only address the issue if popular photo media outlets start bad mouthing the product. It's all about money. If it's only discussed on tech. forums then it's wouldn't effects sales much. Not worth fixing. But if it becomes more prominent in media, they will look into it. I'm going to CES in a week, if I see Panasonic I'll try to embarrass the guys in the booth with this issue.
