12-35mm Lumix ASPH for video -- strange jitter / OIS issue when mounted on a tripod

Anders,

I'm beginning to believe more that this is a systematic issue. One Vimeo user also claimed that he didn't see it. But if he had viewed it at 200% he would have found that indeed it was there:

I guess it depends on focus distance, and of course, the type of footage being shot. (Fine detail will make the problem more visible, obviously.)

Anyway, the odds are there, and it's up to the individual user to decide whether or not this is acceptable. I tested extensively using two different versions of this lens. I saw it about 2/3 of the time. I also scrubbed through older footage I had before I discovered this issue, and I saw it. I hadn't noticed it the first time because the foreground subject was moving, but when I knew what to look for it stuck out to me.

I think this lens is still a good performer for many people, but for particular types of shots I'd use the 12-35mm with caution. Best of luck.
