I have an unhacked gh1 that I purchased from KEH Camera with an ex+ rating. The camera arrived and was in amazing shape. I was recording something yesterday and noticed about 5/6 of the way down there was a thin yet distinct horizontal line in the image. I put it on my computer to confirm and sure enough it was there I tried some shots in other lighting and still had that same distinct line. I contacted KEH and they offered to check it out. I am just wondering if anyone has any idea what might be causing this issue. It really is only noticeable in lower light scenarios, but now that I know its there its all I notice. I tried comparing it to my old hacked gh1 that I've had for awhile and there was nothing similar to it.
