problem with 60D

[KJS]

I have a Canon 60D and recently it has begun showing all photos with a crescent crop on each corner, as if something round is slightly obscuring each corner of the exposure. I have checked the mirror and the full exposure (visually) and see nothing. what could be causing this issue?

It's an ancient camera, not worth a lot. Time to upgrade.

Howdy and welcome! No idea as to what could the issue could be.

Sounds like vignetting - too narrow a lens hood, thick filters, etc. Had you made any changes before this started?

Agree with above post, if you can post images of your camera so we can see the front
Does it happen with all lenses
