GH4 and 14-140 stabilization issue

I've never seen any discussions on any forums focusing on this lens having any compatibility problem with the GH4. It was released several months before the GH4, so one would expect that Panasonic would have most thoroughly tested the lens with the GH4. To date, Panasonic has not released any firmware updates for either this lens or the GH4

Most discussions that I have seen regarding jittery video from the GH4 have revolved around computer hardware and software issues. Problems with underpowered computers with slow video adapter, slow hard drives, and/or slower processor. As well as what video player is being used and what video codecs are installed on the computer.

Here is a test video that a fellow created to test how well a computer and its software is performing in playing video. Download it and play it on your computer. Does the line move smoothly across your screen, or does it stutter at all?

What software do you use to play video clips on your computer? Do you have a pretty high powered system? What resolution is your monitor?

Perhaps you do have a bad lens, and need to have it replaced. If you feel that you have definitely eliminated all other variables, and that the problem only occurs when using this lens, then exchanging the lens sounds like a reasonable thing to try.

Thank you for helping and for good advices.

I tested this issue so that I shooted the same scenes with both (14-42 and 14-140) lenses. I then watched those with potplayer. I have 6-core AMD computer and it shows every 2k and 4k videos fine. So it is not the camera or computer. It is lens related.

My 45-200, 100-300 and 14-42 MEGA OIS lenses shoots pleasing clips. The new POWER OIS superzoom looks fine at first but soon the disturbing vibration spoils the experience. OIS is working because it smooths big movements very well and walking with it when shooting video is better than with the old one. It is quite OK when I move or pan camera. When I try to get steady shot it vibrates fast, mostly in corners. When I shoot with tripod and OIS on it is not vibrating. My high end plasmatv shows every movement perfectly and unforgivenly. I think that the issue is milder in small LCD monitor. I hope that the lens is broken but I fear it is not.

Can anyone with old and new lenses confirm my problem.
