I got out my old F-601 out of its box after a few years . I was holding it enjoying it's weight and the feel of it when I opened the back as nd saw the folowing damage! I guess one of my children had decided to have a look as well. Is this worth getting repaired ? Is this something I could attempt to fix mself ? I have a D40, so if I was to use this, It would be a nostalgia trip more than anything.
