Super noisy images from G80 with lens on adapter

Suspect you are massively underexposing and boosting in post.

Reason for the under exposure likley to be your wrong settings as operating in manual, perhaps you have no live view for some reason?

Not doing any adjustment in post, and JPEGs straight out of the camera have the same problems.

Three lenses were used with the same exposure (shutter, aperture, ISO). The native lens doesn't have the problem, the ones with adapters do.

You have eliminated part of the suspicion by yourself: "camera problem" because the native M43 lens did fine.

Therefore this is very likely down to the lens or adapter issue. It is hard to guess the culprit at this moment. When a lens does well on a camera, it might not be on another. I have a Fotga AF extension tube set. When stacked the 10mm and 16mm tubes on 45~200 mk-I on GX85, it worked fine. However, the same combo got Check Lens error code on GX1. Strange enough it did well if only 10mm or 16mm tube be used... The tube set works perfectly normal on other native lenses on GX1.

However this particular matter should be an IQ issue. I shall look at SOOC jpg that might eliminate any potential problem on RAW conversion. An improper RAW handling could get all sort of IQ issue. I also suggest you to test again using default jpg settings, e.g. NR=0 etc because I had seen enough that -5 NR, insufficient amount of light plus denoise in PP could result excessive and ugly noise effect.
