I never said that it is Roger Ciccala conclusion! I said: "As I understand from all reviews". I think it was pretty clear, sorry if not.

As a man involved in microelectronic manufacturing I have enough experience to said that.

Just facts:

1. It is related ONLY to Pana 20mm f1.7. No other lens have it.

2. It appears only at high ISO, then sensitivity of matrix is very high. Just to remind, that electro sensitivity means not only sensitivity to light, but to every electromagnetic waves.

3. As everybody know it cannot be solved by firmware update – means problem not in programming but in physical impact.

4. And the last – when you see such huge spring (I seen it only at Pana 20mm f1.7, again!) around matrix – it is just common sense to connect it with bonding issue.

Of course I cannot prove it, I need to disassemble my Pana 20mm f1.7 – never do it! But maybe somebody who has enough experience will try to figure it out.

My common sense does not allow me to connect this mechanical part (spring) to anything related to banding

Sorry for you, but common sense comes with knowledge. Of you have an Inductor (coil / spring), and a Current around  - you will always have parasitic Current activated within the coil. It is simply Faraday's law of induction. See follow:
