Anyone heard anything back from Panasonic at this point?

@Kellar42 You can post something

i just bought this lens, and i did the jitter test. ON GH3, 12-35mm @35mm , IS off, on tripod , tilted down 45 degress.

No problem at all!

anyone know if tox's lens is a later serial#?? i know that a lot of XT2.. #'s have shown this problem..

@Zaz good call.

I have this lens now for less than a week, never checked the jitter issue. Just took photos. It's dam fast on AF and with OIS, it's just sick. I was originally planning on an Oly 17mm f1.8, but might explore that option a bit later. For now, this lens does what I need.

wow, panasonic b trippin. I will be getting my lens sometime next week and will post my results then. hope you are able to get a working replacement.

has anyone tried this with stills? seems that any longer exposure photo should come out pretty shit with this issue...

Hi.

Just registered here to share my experience. Got my lense in GH3A kit 14.03.2013 in Helsinki. Serial number starts with XT3AD..... Did video test on tripod 45, 15, 0 degrees down, 35mm and 12mm focal length in next modes: AVCHD(1080, 50i) and AVCHD(1080, 50p) with OIS On and Off. Same time I bought X G PZ 45-175 lense and did same tests for 45mm (45 degrees) and 175mm (45, 15, 0 degrees) OIS On and Off. All was shot with ISO800, Continuos AF ON, Video Exposure mode P. Then copied the video on PC and played back with Zoom player ffdshow video encoder. Deinterlacing switched on for interlaced clips only. There is easy to zoom in by pressing right-side +/- buttons (like in Photoshop). So I checked 100% and up to 400%.

Here are my subjective results:

• At angles 15 and 0 both lenses are rock stable with or without IOS. I cannot see any movement at 400%.
• The 12-35 lense at angle 45 has no jitter at 12mm but at 35mm it does have a circular jitter around one pixel when 300% zoom. In 100% nobody would notice it. OIS On or Off does not matter. At 50i it seems less noticable than 50p. Even 2 of my clips had no jitter in 50i but I guess this just proves the jitter is not always there and not related to the mode.
• The 45-175 lense at angle 45 has no jitter with OIS off. When OIS is On it does have about 1 pixel jitter at 45 and 175 but it is not circullar. It is side to side and has faster frequency at 175.

Also I did a long exposure still shots with 12-35 at 35mm, 45 degrees, 6 sec. I do think the results are as sharp as with same scene and fast shutter speed. Still it appears that with electronic shutter the image is sharper. I did not make many tests with stills because the result satisfied me and I did them before video tests because it was worried me more. I was expecting to find there a blurred result and was happy it was not there. I'm a bit confused why long exposure shots are sharp. Maybe it proves that in video mode there is going something that could be fixed with firmware. But again, I did just 4 shots with shutter speeds 1/25, 4, 4 (mechanical) and 1/50 (electronical). Not a huge statistics.

I was really worried while ordering the camera. At the moment my feeling is that the issue is there but it is not real life issue for my lense copy. But I believe that certain copies may have the jitter more evident. It is a shame if Panasonic would insist that the lense works properly for those users.

I do not publish my clips but if anybody needs them, then tell please which mode, angle etc.. you would like to see.

Nakame78, if you still have problems, and are in the tokyo area, you should go to Panasonics office in Akihabara, it is a little tricky to find, but not too hard. I may be going there soon, and plan on mentioning the 12-35 issues.

I am guessing you have been dealing with Yodobashi. I have never had a simple return even for little items, with them. I have had them tell me stuff that I know had 90day in store warranty was credit only, but soon after they gave me cash because I refused to play their game. It seems to be their policy to make up stories. I suspect often they aren't really talking to Panasonic, just pretending they did thinking it will get you out of their shop. For those in the US, imagine Walmart but instead of their easy no questions ask return system, they go to their manager three times each time coming back with a different excuse why they can't give you a refund or exchange, until finally they do the right thing simply because you are too stubborn to except their BS and understand their policy better than they do. Unfortunately many Japanese are too polite and trusting, and except the BS.

Nakame78, Here is my clip:

My first video uploaded to youtube. I uploaded 40MB MTS. Youtube transcoded the video to bitrate 4 mbps. So it looks more blurry. But if you download and zoom, the effect looks almost same as in original. Less noticable because of extra blur.

@valpopando thanks for your reply. My lens serial # prefix is actually XT2 and it is from Japanese seller on eBay. So should I not worry, then? Are there any further tests I should run? Did you watch it on 200% or more? I noticed above this is common test? I did another test with text so you can see clearer. Note movement in first and last seconds is from my movement turning video on and off:

@test12 thank You ,

Your lens is solid as rock , as ge0rge copy , at this point I dunno , Is not about serial , is not about seller or certain lots or geographical area , is just random ... I was unlucky

@ge0rge yah sorry I miss that in your previous post
