Vesku Posted September 25, 2014 Author Share Posted September 25, 2014 I don't get why you haven't raised the issue with Panasonic yet. Is your equipment stolen or something?? What can I do. I have read many times that when people have complaint to service they usually get an answer that your device is working normally. I have visited 2 times the store i bought my GH4+lens kit. First time all experts was terrified of that jitter and promised to contact Panasonic. Second time about month later they said that it is probably normal behaviour of these lenses and Panasonic people has not answered to them anything else. I need that lens all the time. I can not leave it for repair. After long time they will return it and say it is working normally. My goal is to get this issue well known and then ask Panasonic to make a FW fix.

Inazuma Posted September 25, 2014 Share Posted September 25, 2014 You have a number of options to contact them yourself about the issue. http://www.panasonic.com/uk/contact-us.html This is definitely abnormal behaviour and I would demand a fix. It is probably a problem with your particular lens or the body or both. Quote Link to comment Share on other sites More sharing options...

Or both :) I have found now so many people with this same issue that maybe it is time now to contact Panasonic. Thanks for link.

Vesku Posted September 26, 2014 Author Share Posted September 26, 2014 Can anybody see the famous micro jitter in this video with GH4 and 14-140 II handheld? If you cant see it I suggest to get better viewing equipment. Panasonic has a big issue here. Quote Link to comment Share on other sites More sharing options...
JohnVid Posted September 27, 2014 Share Posted September 27, 2014 Holding off on a GH4 until this is sorted, waiting to see 4K OM footage, what IS options are there on the Samsung NX1 Only optical on the A7s ? tosvus 1 Quote Link to comment Share on other sites More sharing options...
Vesku Posted September 30, 2014 Author Share Posted September 30, 2014 This is an example of the same jitter in 12-35mm 2.8 lens Quote Link to comment Share on other sites More sharing options...
Vesku Posted October 2, 2014 Author Share Posted October 2, 2014 One more unhappy from vimeo: Paul-Louis Pietz Pröve PLUS 4 hours ago Eric, thanks for sharing. The good news is that they're working on it, but the results aren't really improving anything up to this point. since you seem to be in contact with Panasonic, can you maybe hit them back with a couple of things? those being: -OIS works terrible with 14-140mm & 35-100mm lenses, because of jittering Quote Link to comment Share on other sites More sharing options...
karuchie Posted October 3, 2014 Share Posted October 3, 2014 This is a problem of all PowerOIS lens. FZ1000 also have similar problems. I has continued to use the old 14-140 MEGAOIS. There is also a problem that OIS is OFF automatically when close to a stationary state is lens. All panasonic OIS lens. Quote Link to comment Share on other sites More sharing options...
Vesku Posted October 4, 2014 Author Share Posted October 4, 2014 Here is a new test I made: MEGA OIS 14-42mm. POWER OIS 14-140mm. Both handheld at 14mm. Little vibration in POWER OIS but still big enough to ruin the shot: Quote Link to comment Share on other sites More sharing options...
Vesku Posted October 19, 2014 Author Share Posted October 19, 2014 More people are joining the club: @minibokeh from http://www.mu-43.com I'm having HUGE problems with jitter with my 35-100 f/2.8 on my GH4 (click to play):Unless we know that Panasonic is going to be able to help/fix the issue, I'm reluctant to send in the lens and have them sit on it and then send it back with "we couldn't find anything wrong".I'm 100% happy using it for stills, and without OIS video also works without issues.

Vesku Posted October 20, 2014 Author Share Posted October 20, 2014 More examples. In fact every sample in Vimeo or Youtube which contains handheld stationary shootings with 14-140 II has micro jitter. Look this at 0:49. Wide clip with micro jitter.

Vesku Posted October 28, 2014 Author Share Posted October 28, 2014 I had finally today an opportunity to test another 14-140 mm II in a camera store. It behaved exactly the same as my copy. Noticeable micro vibration at 14mm. The salesman said he have talked with Panasonic import people in Finland and they confirmed that they know the issue and Panasonic is maybe working for FW fix. They said also it is a feature, not a fault. So we cant return our lenses or demand a fix. At least I know I dont have a faulty lens and on the other hand I know everyone has badly working OIS. I hope that as many as possible could report to service and demand a fix. I am still wondering why people are not complaining about this. How cant they see it or if they see it why dont they care?

Vesku Posted November 1, 2014 Author Share Posted November 1, 2014 I made again some heavy testing today with my problem lens Pana 14-140 II. I shooted with a short monopod. I attached a heavy weight to monopods lower end and used it leaning to my body (not ground). Image looked very stable in EVF and I made some very slow and perfect pans and moves. When I came home and watched clips the same jittering was there. The OIS is so sensitive that any minor vibration makes it jitter. A good tripod or post stabilization is the only way to get decent shots Quote Link to comment Share on other sites More sharing options...
OliKMIA Posted November 27, 2014 Share Posted November 27, 2014 I have the exact same problem on my GH4 and the 14-140 lens. I have the GH4 for 3 months now but I only did studio work so far. I know how to shot handheld with long focals, no problem on my Canon DSLR, even with a 70-300 on APS-C sensor, I always manage to get decent results. This micro jitter IS a panasonic issue and this is just inacceptable for a video DSLR. I have a $500 piece of junk that can't be use for outdoor, run and gun video work.

Vesku Posted November 27, 2014 Author Share Posted November 27, 2014 Here are 3 more videos showing the 14-140mm v2 OIS vibration. The vibration shows even in low res clips. Quote Link to comment Share on other sites More sharing options...
smokedvw Posted December 2, 2014 Share Posted December 2, 2014 Hi, I was going to purchase a GH4 today to be used with video and pick up the 20mm 1.7 and 14-140 II. Is it better to get the 14-140 I (Mega OS) lens, does it have any issues on the GH4??? I was planning to use this for sports video capturing. Its interesting because I watched some videos of the new 14-140 yesterday and didnt really notice the jitters until it was pointed out in this thread as some videos are more sever than others. Thanks Quote Link to comment Share on other sites More sharing options...
Vesku Posted December 15, 2014 Author Share Posted December 15, 2014 One more vibrating 14-140 v2 lens: Quote Link to comment Share on other sites More sharing options...
pagz99 Posted December 15, 2014 Share Posted December 15, 2014 I shot a wedding with the 35 - 100mm and was gutted to find micro vibrations coming through from what is a (for M43 system) a very expensive lens. This was on a GH3, so it's not just a GH4 thing.. but it might be a Panasonic thing. Has anyone tried the offending lenses on a Olympus or Black Magic body to see if the footage from those cameras also has the jitter? Quote Link to comment Share on other sites More sharing options...
tosvus Posted December 15, 2014 Share Posted December 15, 2014 I shot a wedding with the 35 - 100mm and was gutted to find micro vibrations coming through from what is a (for M43 system) a very expensive lens.

Has anyone tried the offending lenses on a Olympus or Black Magic body to see if the footage from those cameras also has the jitter? There is no reason they shouldn't have the same issue. I have it on my 35-100 with gh3 as well by the way. Vesku just posted some testing regarding mercalli v4, and I tested it a bit myself - it is a way to save stuff you shot that you need fixed, but paying over $200 for software to correct something Panasonic should have taken care of in the first place kinda sucks. If you use Premiere, you can try warp stabilizer, your mileage may vary.. I did some quick testing but didn't get anything really great out of that. The Mercalli demo seemed to work better. You mention Olympus, and of course the work around for those are to disable OIS on the lens and just use IBIS. Quote Link to comment Share on other sites More sharing options...

Thanks i don't own either, but based on everything I have read, the v1 does not exhibit the issue that the v2 has in terms of micro jitter.
