GH4 and 14-140 stabilization issue

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.
