Just wondering if someone could confirm this for me.. I'v read that the OIS issue is only present when shooting between shutter speeds of 1/80 - 1/200 is this correct? I plan on using this lens for video will I have any issues with the OIS for video or is it only with photos? I read that the the issue may be caused by vibration from the shutter when taking a photo? Can anyone confirm this? And wouldn't that mean that there shouldn't be a problem with the OIS for video????? Thanks. I'll be using this lens on a GH3 (if that makes any difference) once it arrives, I have it on preorder.
