Still, "Blaming the firmware for malfunctions in a camera has a low likelihood of being the issue."
A lot less stuff for 2018 but still a lot of Canon stuff. Along with, a lot of other stuff.

Re: 5d mk iii Problem SOS!

I'm guessing this problem was solved long ago. However I have managed to replicate it in my 5D Mk III twice this week, when suddenly the camera has refused to operate live view and any of the buttons including menu in any mode other than the A+ mode.

The solution seems to be to go into A+ mode and press the menu and Q button simultaneously. If this does not work go back to Manual mode and press menu and Q simultaneously. I've found this magically reinstates the menu and all button functions. If the menu comes back on but the buttons don't work then go to the spanner menu in the menu (not available in A+ mode but is in any other) and select factory reset under menu 4. You'll have to reinput any special settings you had but the camera should then be fully functioning. I needed to do this last step the first time it happened, but today pressing Menu and Q simultaneously was enough to restore all function....

Good luck!

Re: 5d mk iii Problem SOS!

Hi there ! Yes this problem was solved a few months ago, a lot of this I had already tried as I ready about it on another forum. It did not work. The problem was a failed drive inside the camera. It had to get fully rebuilt which cost around $800 but now it’s basically a brand new camera.
