I notice on most (but not all) of the images taken with my new D800 there is a vertical line of colorful pixels bisecting the frame. The line is always at the same spot. It seems more noticeable when shooting at longer exposures using live view but also can clearly be seen when handholding at faster shutter speeds. I'm going to contact B&H for an exchange, but I wondered before I do if anyone else has noticed such behavior or could tell me what I'm seeing. The line is visible on the attached image to the right of the window.
