pietz Posted August 31, 2014 Share Posted August 31, 2014 i can relate. i love the 14-140mm II on run and gun shoots and it has been a great performer on my G6. the 6MP resolution is not a negative point in my book. i still think that 95% of the people shoot 4k and master in full hd, so 6MP is plenty. with the GH4 the OIS feels worse, although not as bad as your tiger sample clip. kinda strange, lets hope for an update. ive never liked the 12-35mm. its not versatile enough for run & gun and not fast enough for commercial shoots. above all its rediculously overpriced, i dont understand why so many videographers fancy this lens. however if the OIS is better with the 12-35mm, it jumps up the latter a little bit.

leeys Posted September 3, 2014 Share Posted September 3, 2014 Again, are you using it at beyond, say, 50mm? At 140mm the stabilizer has to work extra hard. Also isn't the 14-140mm a Mega OIS lens? Quote Link to comment Share on other sites More sharing options...

Also isn't the 14-140mm a Mega OIS lens? Please read previous posts. My 14-140 II has POWER OIS and it jitters at every focal lenghts, every shutters speeds and every framerates and every resolutions! It is the lens that jitters so nothing else matters. I cant believe that not many can figure this matter. Maybe average people are half blind or not caring about quality in practice. Or maybe every videographers uses a tripod.

Vesku Posted September 3, 2014 Author Share Posted September 3, 2014 Or maybe just most people use it as a stills lens. Because it cant shoot stable video.... Quote Link to comment Share on other sites More sharing options...
Vesku Posted September 22, 2014 Author Share Posted September 22, 2014 My workflow is now with handheld 14-140mm shots: Sony Movie Studio 13 and light stabilization for EVERY clip. That is very time consuming and difficult because that editor lets you stabilize just one clip at time and then I must wait. Then second clip and waiting......etc... I have shooted handheld GH4 30P 4k files with relatively high shutter speeds (1/100s - 1/160s). With slow camera movements and light stabilization (Sony MS 13) motion and stability is very good when watching with modern TV with motion enhancements. 30P motion is very convincing and lifelike if there are no rapid action or panning. When I stabilize GH4 60P files shooted with high shutter speeds the results are jello free and smooth because GH4 60P has very low rolling shutter effect and there is no motion blur to ruin flawless motion experience. Almost all that convincing motion experience is lost when watching with computer monitor because it smooths every little movement to SD level of resolution. So result looks like sharp-soft-sharp-soft depending on camera or subject movement. Quote Link to comment Share on other sites More sharing options...
Wynand Posted September 22, 2014 Share Posted September 22, 2014 Very interesting. I have a 12-35mm (new) Lumix on my GH4 and I see ZERO stabilization with the IOS switched on... Do we have a problem here? Quote Link to comment Share on other sites More sharing options...

Do we have a problem here? Do you mean zero jitter or vibration when OIS is on. Look very carefully handheld shots with OIS. I think that there is little fast jitter with that lens. Yes I have a big problem with my lens. I cant return it because it is the way it works. I like all the other properties of that lens, great photos, light, IQ in video, fast focusing, etc. I hope that FW update is coming... I tested 12-35mm in a storer and it vibrated the same way as my 14-140 II. Quote Link to comment Share on other sites More sharing options...
tosvus Posted September 23, 2014 Share Posted September 23, 2014 The 35-100 is also been reported to suffer from micro jitter. Seems Panasonic has some explaining to do... There was talk about resolving power for 14-140. Indeed if it I only approx 5MP, that falls well below the 8 MP in 4K(4xmore than 1080p) Quote Link to comment Share on other sites More sharing options...
tosvus Posted September 23, 2014 Share Posted September 23, 2014 Hi, I added a video to vimeo to show the issue on the 35-100. I think you will find that the issue is very similar: 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) It will possibly be available at > in 45 minutes or so, but I'm heading to bed now... If it doesn't work, I will update in the morning. Quote Link to comment Share on other sites More sharing options...
Vesku Posted September 23, 2014 Author Share Posted September 23, 2014 Hi, I added a video to vimeo to show the issue on the 35-100. I think you will find that the issue is very similar: Thank you for supporting my crusade against Panasonic POWER OIS. We must ask for a FW update. How that can happen? These are very expensive lenses with "HD" video certification. It is not right to accept that kind of bad quality. I am just wondering why people cant see that issue with their lenses. Are they blind or do they think that handheld video can not be stable at all. By the way I made a review of my GH4/14-140 II kit to my stores web page about a month ago. Since then no one has bought that kit. Quote Link to comment Share on other sites More sharing options...
tosvus Posted September 23, 2014 Share Posted September 23, 2014 No problem Vesku, I agree that this is completely unacceptable. I also posted a review on a major site describing this. I plan on making a separate thread here on EOSHD as well. Quote Link to comment Share on other sites More sharing options...

However when I shoot in C1 auto FHD 1080 200mps, the IOS is working OK..... very confusing to say the least! Quote Link to comment Share on other sites More sharing options...

My OIS is smoothing big camera movement but adds jitter. Did you shoot handheld holding camera stationary. Look for very little and fast micro vibration.

Vesku Posted September 24, 2014 Author Share Posted September 24, 2014 I have been playing with Prodad Mercalli V3 tryout and my jittery 4k clips stabilizes nicely. It would be good if that program comes as a free extra when on buys a POWER OIS lens :) Quote Link to comment Share on other sites More sharing options...
tosvus Posted September 24, 2014 Share Posted September 24, 2014 Prodad seems interesting, but as you say - it is too bad we have to buy software to correct an issue that Panasonic should deal with. (Plus I suspect it can never be a 100% fix compared to if they manage to fix the jittering in lens..) Quote Link to comment Share on other sites More sharing options...
Vesku Posted September 24, 2014 Author Share Posted September 24, 2014 Mercalli V3 stabilizes nice multiple clips but there are issues: 1. When stabilizing multiple files Mercalli uses automatically values it wants for every clip. So I cant affect what it is doing. Usually it crops too much for my liking. 2. It renders GH4 0-255 files to 16-235 files so I loose a lot of color information. 3. There is no option to save my own stabilizing profiles for quick use. One option is learn to like that jittery and vibrating "look". After all many people still prefer 24P stuttering and juddering "look".

tosvus Posted September 25, 2014 Share Posted September 25, 2014 I believe you mentioned Adobe Warp stabilizer. Aside from being a pain to use, how did it work in terms of removing jitter? My bad, you use Sony solution? Adobe Warp stabilizer has a good reputation so I will give that a go...still, a pain... Quote Link to comment Share on other sites More sharing options...
Vesku Posted September 25, 2014 Author Share Posted September 25, 2014 I have no Adobe video software. The new Premier elements is worth trying I think. Quote Link to comment Share on other sites More sharing options...
Inazuma Posted September 25, 2014 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?? Quote Link to comment Share on other sites More sharing options...
