Re: Panasonic Lumix G7 lighning problem

It is actually hard to say whether there is a problem with the camera/lens or not. When overexposing the light sources several stops/EV, these kind of things always become visible. It looks like a greasy lens element, but it's hard to say for sure.

Increasing the brightness of the dark areas in the photo makes it worse.

I would like to see a picture of the front and especially the rear surface of the lens. If someone has touched the rear lens element with greasy fingers, it's definitely possible to clean it, but personally I cannot give any decent advice. It is also possible that this has happened in the past, and something has went wrong during cleaning (two sand particles in the cloth used for cleaning, too strong chemicals...).
