My GH5 is now displaying the micro jitter problem again as I reported back in March 2017. My GH5 has ver 1.1 firmware and my lens (Leica 12-60mm f2.8-4) has the updated ver 1.1 firmware.

I only noticed this today after filming my friends son outside my house using my GH5 handheld in 4K 50p mode. I will run more tests in the morning.

Having had a look at V2 FW info this issue has not been addressed but once again I will enquire about this tomorrow.
