The fast jitter might appear because Power OIS is optimized for high megapixel sensors that bin most of the pixels. The hand-shake reduction can thus work by picking adjacent pixels that align with the binning sequence.

Since the GH4 sensor uses full read of a cropped area of the sensor, without any binning, perhaps the Power OIS simply cannot operate the same way, thus creating a distortion.

Meanwhile, if the FZ1000 stabilization was optimized for its fixed lens, perhaps the jitters aren't as pronounced. Maybe someone should take one to a zoo and shoot a hand-held zoom shot of a tiger under similar lighting conditions!

At any rate, that is one $0.02 theory to consider.

This sort of thing may not be reported, or ever discussed, in forums where the users shoot on tripod at night all the time.

Panasonic cameras do not bin the sensor so why make a lens to work for binned video.

The lens wobbles, thats all. very odd for Panasonic to make a lens for video which jitters and wobless because older lenses do not do that.

The funny thing is that it jitters as much at 14mm than at 140mm !!
