tosvus Posted September 23, 2014 Share Posted September 23, 2014 Hi, I added a video to vimeo to show the issue of Micro Jitter on the Panasonic 35-100. This is basically a Power OIS flaw that shows itself clearly when doing handheld video with stabilization enabled. This issue is fairly widely reported, and similar issues have been reported for the Panasonic 14-140. Earlier the issue was apparent on Panasonic 12-35 f2.8 as well, but Panasonic did provide a firmware fix to that particular lens. It seems logical that similar fixes could be done for these two other lenses as well, but Panasonic has so far not acknowledged the problem. This is perhaps because a large percentage of users are mainly taking photos, not shooting video, so it has not so far affected ratings or most reviews to a large degree. (It works fine for photos) Comparing 4 lenses, around 35-45mm, to see how each handle in terms of OIS when used handheld. Shot with GH3 in Ex-tele mode (which zooms in), then Premiere was used to crop into 4 different squares. All were shot at 24fps w/125 shutter speed, 1000 iso, and either f4 or f5.6 aperture. Original clips were stored in 1080p24 at 50mbps. Absolutely no processing of the video was done other than cropping. As is evident, the 35-100 has a very clear micro jitter issue, while even a cheap 14-42 kit lens does not. Lenses in test: Panasonic Leica 42.5mm f1.2 "Nocticron" Panasonic 45-150 f4-5.6 (shot at 45mm) Panasonic 35-100 f2.8 x-series (shot around 40-45mm) Panasonic 14-45 f3.5-f5.6 (shot at 45mm) The first test is available at " title="External link"> Quote Link to comment Share on other sites More sharing options...
andy lee Posted September 23, 2014 Share Posted September 23, 2014 just a note: - I see you are doing these tests in ex tele mode? that makes the problem x2 worse as you are making the lens x2 longer doing this most people will not be using ex tele mode to shoot video ....just a thought can you do a test in normal filming mode not ex tele to show how bad the gitter is normally when filming big thanks Andy Quote Link to comment Share on other sites More sharing options...
tosvus Posted September 23, 2014 Author Share Posted September 23, 2014 Hi Andy, I Will do a video that shows normal mode as well, but from this comparison clearly shows an issue that their other lenses do not exhibit. As for ex tele, it is a video only feature implemented by Panasonic and while some lenses are highly usable in this mode, and should be, the 35-100 is not. I think it I a useful feature, and I'm sure many use this occasionally to increase their reach. Also, I believe people shooting 4K can forget cropping in post if using this lens, which is one of the reasons for shooting 4K today. I will update the post later, but again, this is clearly an unnecessary flaw in an expensive product. Quote Link to comment Share on other sites More sharing options...
andy lee Posted September 23, 2014 Share Posted September 23, 2014 thanks for pointing this flaw out Tosvus its good to know about it - I'm interested to see more on this as I was considering the 35-100mm 2.8 just for its OIS ...I may not get one now .....

hoodlum Posted September 23, 2014 Share Posted September 23, 2014 I wonder if this will impact the LX100 as it has Power OIS. Quote Link to comment Share on other sites More sharing options...
tosvus Posted September 23, 2014 Author Share Posted September 23, 2014 I wonder if this will impact the LX100 as it has Power OIS. Yes, it will be interesting to see. It might be less of an issue since the lens is considerably lighter/smaller on the LX100. Quote Link to comment Share on other sites More sharing options...
tosvus Posted September 24, 2014 Author Share Posted September 24, 2014 Added second test. Note that the streaming is only 360p or something - they have a stupid limit of 1 HD upload per week at Vimeo for free users... However, for a few days, the 1080p version is available for download.

Vesku Posted September 30, 2014 Share Posted September 30, 2014 It is good that Panasonic hears our official complaints of POWER OIS lenses. I wish that everybody with these issues will send an email to Panasonic service. They may consider a FW fix if it is possible. I made my post too to Panasonic and the answer was like yours. Before fix the software stabilization is our way to go. I have got great results with Mercalli. The bad thing is that it changes GH4 0-255 files to 16-235.

karuchie Posted October 3, 2014 Share Posted October 3, 2014 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 3, 2014 Share Posted October 3, 2014 There is also a problem that OIS is OFF automatically when close to a stationary state is lens. All panasonic OIS lens. Hi What do you mean? I have not noticed that OIS goes off. When OIS is off image jitters even more handheld but that is handshake. Quote Link to comment Share on other sites More sharing options...
Gorazd Posted January 21, 2015 Share Posted January 21, 2015 Hi,Panasonic has just released the new 1.2 firmware for the Panasonic 35-100mm f/2.8 Lumix G Vario Zoom Lenswhich had issues with micro jitter when you use it with GH3 or GH4 when shooting video and the Power Optical Image Stabilization in the lens is used.The official links for Win and Mac files:http://av.jpn.support.panasonic.com/share/eww/en/dsc/fts/win/HS35100V12.exehttp://av.jpn.support.panasonic.com/share/eww/en/dsc/fts/mac/HS35100V12.zipBest regards,Gorazd Quote Link to comment Share on other sites More sharing options...
macnerd Posted January 22, 2015 Share Posted January 22, 2015 i had the same problem, sent it back to panasonic and they seem to be aware of the problem with the lumix 12-35mm lens Quote Link to comment Share on other sites More sharing options...
tosvus Posted January 23, 2015 Author Share Posted January 23, 2015 Ok, I got to try it out. There is DEFINITELY an improvement, though on my copy, not eliminated. I would say doing a quick test, that it is still not as good as the other lenses I tested originally, but in normal mode, I think it is acceptable. In tele-ex, while improved a lot, I would not want to shoot hand-held still, so keep a tripod around for that use at least.Still, nice to see Panasonic trying to fix the issue. It is probably the best that can be done via a FW update alone. Quote Link to comment Share on other sites More sharing options...
sgreszcz Posted February 9, 2015 Share Posted February 9, 2015 tosvus,Thanks for the update on this. I upgraded my 35-100 firmware just before shooting a bunch of video. Previously, I only used the 35-100 to shoot video with OIS when mounted on my E-PM2. I thought that is how crappy OIS is by nature for video (when comparing to my E-M5 at the time), that I never tried again.After filming with the firmware upgrade on my GX7, it seemed a bit better, but much worse than my LX100's OIS. I really need to do a comparison between the LX100 and 35-100 at 70mm. I still think there is too much jitter in the 35-100 though but as it is my only OIS lens, I can't really tell.I'm thinking hard swapping the GX7 with the EM-5 II (for telephoto), with the only downside being having to match shots from the LX100.

sgreszcz Posted March 7, 2015 Share Posted March 7, 2015 I tested the OIS stability in video with my Panasonic GX7 with the 35-100/2.8 @70mm vs. my LX-100 @70mm. You can still see much more micro-jitter on the 35-100 than in the LX100. Shame, really as it is a great little zoom lens for stills.https://www.youtube.com/watch?v=R1sNjEfD3GE Quote Link to comment Share on other sites More sharing options...
