Always kept in a bag when not in use. The only blemishes I know of are pictured on the top plate on the pentaprism housing. The camera has had its mirror repaired since it fell out, which was a common problem on these old EOS 5D cameras. The focusing screen has some scratches in the top-left corner from when the mirrow came loose during shooting. This is easily replaced and compatible focusing screens are still widely available as all EOS 5D generatios share the same focusing screen shape. It does not effect image quality, only viewfinder.
