@Tron - I would be able to capture usable hand-held video at the shorter focal lengths covered by the 100-400mm lens, assuming the Power OIS doesn't have the same jitter as the Power OIS on 35-100mm X lens. I'm really interested to see test results.
Panasonic 100-400mm info from Swedish photo fair, comes in late february, priced at 22-23000 SEK which in Sweden is about the same price as the GX8 + 12-35mm kit. another reference is the Panasonic Lecia Nocticron which cost 15000 SEK in Sweden, so It will be really expensive. “
@v10tdi The OIS mentioned in this spec is intended for still photos being taken handheld. Even with the smoothest IS you're not going to be able to hold a stable video frame with the 100-400mm. The shot will be wandering all over the place out past 150mm and the video will look very amateurish. You gotta have a sturdy tripod if you want decent looking vids at extreme focal lengths, there's no way around it.
@sgreszcz 35-100mm OIS issue was fixed back in January - http://www.learningvideo.com/panasonic-35-100mm-ois/
Leica also usually mean that it will be pricey.
