I bought a Panasonic GX85 today. One of the first questions I wanted to answer is, does this camera produce the infamous noise-pattern banding with the 20mm prime lens? (For an example of what I'm talking about, look here.) I performed the same tests I did with my Olympus cameras - low light, high contrast, various ISO and aperture settings, mechanical and electronic shutters. So far, I have been unable to produce banding with the GX85 and 20mm lens. There are various reasons why the new camera might be immune. The sensor could be a Panasonic sensor - though rumors suggest it's not. It could also be that Sony has produced new sensors that aren't as susceptible to the problem. The new shutter mechanism could also avoid the issue. Who knows. Results matter most, right? I'd love to hear of your experiences with the new cameras and the 20mm lens - in particular, the GX8 and PEN-F, as well as the GX80/85/7-ii. Please share! Thanks.
