Why do my photos have a bright horizontal band at faster shutter speeds?

My Canon EOS-1Ds Mark II has suddenly started producing a bright horizontal band across the middle of most images. It happens regardless of which lens I use or what I’m photographing, so it doesn’t seem related to the lens or scene. The band appears mainly at shutter speeds faster than about 1/60 second. What is likely causing this, and is it repairable?

Looks like a shutter malfunction (which fits with it only appearing at certain shutter speeds). The shutter is made of a series of metal blades, it looks like one of these blades is misaligned, which is exposing that part of the sensor for longer than it should be, hence the bright area.
You can have the shutter replaced at a Canon service centre.

Generated from our catalog & community — verify before relying on it.
This is most likely a shutter malfunction, not a lens problem. Since it appears with different lenses and mainly at faster shutter speeds, the shutter mechanism is the key clue.
On this type of camera, the shutter uses moving metal blades/curtains. If one blade is misaligned or not traveling correctly, part of the sensor can be exposed longer than it should be, creating a bright horizontal band.
Yes, it is a real fault, and the usual fix is shutter service or replacement by a Canon service center or qualified camera repair shop.
