I own the Panasonic GX7 and use it with Panasonic 14mm, 20mm, 25mm and the Oly 45mm lens. When I take photos under certain lighting conditions I see lines across the image. I have checked the manual and see where they tell you to use shutter speeds below 1/100 what about still images? Is this condition different depending on which lens you are using? Both the Oly and Panasonic seem to be using the same type sensor (not the same sensor), and Panasonic says in their manual that this isn't a fault with the camera (under video/movies I can't find anything about still images). Do you Oly users also have this problem. Very upsetting to come back from a shoot only to see that part of the take has these brown vertical strips going across an image. Only certain type of lighting has this problem.

Hi Charles.

it sounds to me like you are using the electronic or silent shutter in areas with flourescent lighting. If you are that is the issue. Regardless of the chosen shutter speed the total sensor readout happens in 1/10 or 1/15 a second. This causing banding with flourescent lighting. Switch over to the regular shutter and you should no longer have this issue. When shooting video it is important to keep your shutter speed set at a reciprocal of the lighting refresh rate in the country you are in. 60hz or 1/60 in the usa and 50hz or 1/50 most other places. Or 1/120 and 1/100 etc
