Hi guys, Before I'm taking my XT3 for repair, making one last check: My ISO dial apparently stopped working - the ISO level is on 320 and turning the dial just won't do anything anymore. Also, tried to set the command dial to change the ISO with no luck, and I'm pretty sure I've adjusted everything correctly in the menu. The only time the ISO DO change is when I put the camera in F-LOG, then it changes to 640. Any ideas? I'm pretty lost here.
