https://www.mu-43.com/showthread.php?t=69367What kind of problems? If you are using a tripod, OIS should be disabled.
12-35mm issue was very strange. POWER OIS was jittering video when shooting with tripod and OIS was switched OFF!! FW corrected that. I tested updated 12-35mm lens in my store and it jittred the same way than my 14-140mm II lens. So there is a common issue of POWER OIS or there are lots of bad copies of lenses.I recall that v1.0 firmware for the 12-35 had this issue, but was corrected soon thereafter. I have the 35-100 and I have not seen or experienced this. Many people will leave OIS on,when on a tripod. Most of the camera operating instructions did inform the user to disable it. As a general comment, I would make sure that both camera and lens have the latest firmware. Check with Panasonic.net in the "Support" section.
More info and tips here:Tries last night with 35-100 and I don't see any jitter. Please explain the exact settings to make this happen.
So reading through this, it seems this occurs in an extended tele mode and video might be cropped? This might explain why I don't see it. This effectively increases it by at least twice. I'm going to repeat the test, but so far it's not been a problem for me. Interesting none the less. Thanks for sharing.More info and tips here:
Fast micro jitter shows best when shooting handheld stationary video (without moving camera). If you cant see that jitter at all there must be lots of bad copies of that lens with other users.
No it happens in normal mode as well, but it is less disturbing. (The second video shows it in normal mode, and it visible still). You can try to replicate with similar shutter/is/aperture.So reading through this, it seems this occurs in an extended tele mode and video might be cropped? This might explain why I don't see it.

Thanks for caring and telling about the issue.I just reached out to someone I know at Panasonic. He explained, while we were aware of the problem that the 12-35 had, and was corrected, to date we have not received any 35-100's or 14-140's at our service facility in TX for this problem. If anyone has a lens with this problem it should be sent there with a detailed description of the camera it's used with and the procedure to replicate this problem. We need to collect some internal data from the lens so it can be analyzed by our factory in Japan.
People are complaining, but have they actually reached out for assistance?
Vesku, assuming such things is not an accurate picture of the situation. I reached out to my contact, a very close friend, at their service in the US. I'm told that to date, not one 35-100 lens was received for this condition. Nothing is under study because none were received to evaluate. My experience about much of what we read in these forums is that many times details are embellished, mildly exaggerated, with the belief of receiving faster corrective action. And some times people who don't even have the problem will complain, thinking more complaints = faster action. When such facts can't be substantiated the matter (and the source) looses credibility. In the US we call this "crying wolf". I don't see any jitter on my 14-140, so it's unfair to say all lens have the problem. I suggest that if anyone has the problem they send it in so it can be evaluated. That would be the first step to getting Panasonic's attention and their enthusiasm to look into it.Thanks for caring and telling about the issue.
I think that every 35-100 and 14-140 lens has this issue. They may have these lenses in the factory
I have read stories of 35-100 sent to service due to jitter and the service said it is working normally. I have contacted Panasonic Europe service with my issue and I got an answer that they are studying the issue. I cant believe they are so blind not to see that jitter.
