Nikon D3200 Viewfinder
So, in the last few days my D3200 has developed a strange problem. When I look through the viewfinder, I can see two lines stretching "into" the viewfinder, converging towards the image. I am pretty sure these lines weren't there before. The lines are displayed below the image and start closer than the image. Unfortunately I wasn't able to take a picture. Does anyone know what the problem might be?
