GH4 Strange strobe und jerking in GH4 pans with Lumix 12-35. Did anyone else notice this?

When panning with Lumix 12-35 I noticed some jerking. It almost looks as if the OIS was still on.
I didn´t investigate into it, but now I read in the commentaries of the Philipp Bloom blog that someone else became aware of this:

"I noticed a big defect doing pans... It´s like a stroboscopic effect... Shot with the Lumix 12-35mm f2.8 at 25p in c4k mode and the result is pretty bad moving around. It´s doing it in every single mode (In 50i mode it´s not doing it)."


Did anyone else notice this?

are you certain it is not a playback issue? many computers and some players are not quite up to 4k playback yet.

If it's not doing it in 50i and is doing it in 25p then maybe it's just stutter. If you are panning fast any 25p footage will stutter. Film does the same thing. I think the rule of thumb is that it should take 7 seconds to pan something from one side of the frame to another. Try slowing your pans and see if you still have it.
