Re: 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.
