I've got a 5D mark II that is about six months old. For about a month now I've noticed what looks to be a huge piece of lint or other obstruction in the viewer. It's not showing up on the images, so it's NOT on the sensor.


I've removed the lens to eliminate that. I cleaned the outside of the viewer, (the part you look through), the piece with the focus targeting and the mirror. I even flipped the mirror halfway to get in between the two reflective surfaces... No Luck.


Has anybody ever had an issue like this? Like I said, it's not affecting the images, but it sure is annoying to see the obstruction in the viewer.
