I am going from a 50 D to a 5DmkIII. There are a lot of settings changes. I don't know if I changed some setting that turned off the dial just behind the shutter release, Or if camera is broken. It was working, now it is not. I have gone through all the settings and i can't see a mode that causes the dial to stop working. Please advise me what I hit to turn that dial off.
Thanks!
