I do not think this is the lens to blame. I think this is a sensor problem. Can you, please repeat you findings with different lens under identical conditions (especially ISO 6400)?

doesn't the Panasonic GH3 manual acknowledge the possibility of stripes appearing when using the 20mm and high ISO?

I have GH2. And I do not care... if Panasonic acknowledged this, it sounds more like a disclaimer (just in case someone tries to sue the company).

They do acknowledge it in the manual and the reason is not that this is something they could be sued for (or avoid being sued for by mentioning it in the manual).

I've seen it with many Panasonic products. Manual for Panasonic microwave states that Panasonic is not responsible for fire caused by drying wet shoes inside MW.

Again, if banding appears only at high ISO, it is not the lens, it is a sensor. If it could be a lens, you should see banding at any ISO.

If you see it with this particular lens and this particular sensor, not with other lenses on the same sensor and not with the same lens on another sensor, it is the lens and the sensor.

As to ISO, you can see it with the camera set to any ISO. It's just a matter of how hard you push the shot in PP.

When I push hard PP, I have this banding with 14-45

Any camera with any lens will produce banding if you push hard enough. That's not the point. The point is that the 20 is more prone to banding than other lenses when used with the particular sensor at issue here (not other sensors).

"More prone" - I try to explain this with simple suggestion that we use 1.7/20 more than any other lens for low light. If you remember, all this banding issue started to float around before other fast lenses came to life, so 1.7/20 was the only one...

That might have been the reason but wasn't. There have been lots of controlled testing, shooting the 20 side by side with other lenses under the same conditions. These tests show without any doubt that the 20 is more prone to banding on the particular sensor at issue here (not others).
