As with other canon cameras..this is starting to seem common place...
I don't own a mark III...would like to...but try updating the firmware to the newest available...the link is at the top of the forum..
It may help..
Good luck

I wouldn't say this is any more common than it was three or four years ago, just that they ship several time more cameras (and a lot more cameras are being shipped to people who are less than semi pro, most of which overreact at every inconvenience). The percentage of actually broken cameras hasn't changed, but since there's more of them, there's more broken cameras. And now, even more so than three or four years ago, people take their complaints to multiple forums that they normally don't post in. Since people that want to complain about a problem are much more likely to write about it than people who are perfectly happy with their cameras (and are out using them rather than here complaining), it seems to be a bigger problem than it actually is. Not dissing OP at all, he's got the right ideas (return, repair, not sitting around and sulking), rather saying there are too many people not like him.
This is simply a (bad) luck of the draw type thing. It worked perfectly fine when canon tested it, and when you had it at first, then it went sour. My mkiii went sour after a week, the rear dial just wouldn't work (first call i made to canon they suggested to reinstall the firmware until i cut them off and told them to press the button i needed to turn the wheel, second call the guy was great and said that he'de send a box with labels, put the camera in there, fill out the sheet that was inside, and to send it). I sent it to canon and within a week they had the camera new as can be, and even new firmware too (the wheel felt different, so they did end up replacing it).
