If you look at these images from my 1Ds Mark 2, you will notice a faint, diffuse desaturation line across the top of each image. It began as an intermittant problem three weeks ago, but has now become constant. It's almost as if the CMOS sensor has moved from its proper position.
Does anyone have any good ideas what might cause this problem?
The camera is going back to Canon, but I thought I'd ask anyway.
