GH4 POWER OIS jitter issue

I have GH4 and 14-140 II lens. When I shoot video handheld and try to keep it stationary and steady the OIS is generating rapid vibration or jitter. It shows clearly in 2k and is bad in 4k. I have seen that jitter also with 12-35mm and 35-100mm POWER OIS lenses in Youtube or Vimeo. All my MEGA OIS lenses (14-42, 45-200 and 100-300) introduces no micro jitter. It is funny that if I shoot carefully I can get more stable video handheld with 100-300mm at 300mm! than 14-140mm II at 14mm.

Can someone test this? Do I have a faulty lens? Do I have too critical eyes?
 
Generally, as a rule of thumb. You disable any stabilization when using a tripod or any "stabilizing" device with your camera.
This eliminates that annoying "stutter" as you pan. Im saying this only because the "OIS" is the obvious culprit.

Now onto "handheld" and using Super Zooms, they have a much large "stabilizing" mechanism built in because they need to make larger corrections. The mini zooms like the 14-42, its not as large.
You also may want to turn "continuous focusing off" which may cause the lens to try to stay at a specific subject point (i.e. someone's face)

This is all hypothetical, as I don't know exactly whats going on inside these lenses.
But from my generally use of my Nikon D600 taking photos. With the 70-200 f2.8 super zoom, it'll over correct when i "point focus" and move the lens. Where my 24-70 f2.8 doesn't have that issue.

Best bet, is to get the "kit" lens (14-42 I do have it and don't have that issue, plus its like $130 only) and use that in OIS mode... and switch OIS off when using your 14-140mm. (at least the first half of that zoom range)
 
If you have 14-140 II in hand could you please make a very simple test. Shoot handheld at 14mm a stationary video clip (without moving camera) and see if the result is clean without any vibration. It is impossible for my 14-140 II but easy for my 14-42.
Thanks
 
For handheld video, the best OIS lens I've used is the Leicasonic 14-50mm f2.8-3.5. It's an older 4/3rds lens that requires an MFT adapter, but it's totally worth it. The OIS never jitters, it has a touch like molasses that you can almost feel when you use it. Here is an example, totally handheld, not even with a monopod:

Thanks for help

Is that an old lens? How can it be that older lenses has better OIS than the newer ones?

Your example is not very informative because camera and subject are moving and video is also soft. Hard to see OIS jitter properties when there is no stationary situation. That jitter I talk about jitter shows in "stationary handheld video shots".
 
My cheapest and oldest Panasonic 14-42mm lens has best OIS I have had. At least 3 times steadier than 14-140 II in small movements. 14-140 is though better with big movements. My 14-140 II is almost useless for video handheld. Needs software stab in every shot.
 
I found another example from Youtube.

No tripod. See how image is very still like in tripod but jitters still badly. If you cant see this micro jitter and if it is not disturbing I wonder what are your quality expectations and standards. Is this acceptable?

Is that weird that I can shoot handheld more stable videos with 100-300 at 300mm than 14-140 II at 14mm !!!

How that can be possible. In fact when I use ex-tele crop at 300mm handheld (about 1500mm FF eq) it looks like shooting at 14mm with 14-140 II.
 
I bought the 100-300 OIS lens a few weeks ago and it has exceeded my expectations. I notice it is made in Japan.

Would be interesting to see an example of your shooting with the 100-300 at 300 using ETC while handheld. Very hard to imagine any 14mm lens performing on par with that in terms of comparing for a steady image. Are you sure you're not exaggerating just a little? :)

It is about 50 times the magnification (300mm extele vs. 14mm). I cant hold the frame as still at that magnification but the fast jitter looks somewhat the same as with my 14-140mm at 14mm. I am very confused why people cant figure that jitter with their lenses. Why are they willing to accept bad results? Maybe they use small cheap LCD screens which softens all motion in videos.
 
I noticed one more interesting thing. When shooting with old 14-42mm in 4k the result is cleaner than with 14-140 II because there is no jitter which consumes additional bitrate. GH4 about 80mbs 4k video is at the edge of macroblocking and codec "roughness" and when I shoot with 14-140mm II there is constant movement in frame (jitter). The codec must work harder to record that jitter and the result is not clean.
 
I've haven't noticed this with my 14-140 (first version) except in certain slow panning situations where you might expect it. I'll take a look with mine. You're sure it's not tripod vibration?
 
of all the Panny lens I own, 12-35mm, 42.5mm, 14-140mm(V1), 35-100mm and 100-300mm, only the 35-100mm has the OIS jitter problem.
I brought it in to Panasonic and they claimed that the OIS is working fine. I have since gave up using the 35-100mm OIS.
