just came across the link of errors
Error 80 is so miscellaneous in its description from Canon
That link leads to...
Error 80 means "Malfunctions related to the electric control or images have been detected"
That's not much help. I shot a couple hundred more pics today with no problems. Hopefully there is nothing physically wrong with the camera. Might be something a future firmware update can fix. There do seem to be too many people having the issue.
