I'm having an issue with enabling self-timer in my 1dx. When trying to select any self-timer options, they appear disabled.
Any ideas, why this could be the case?
Go to Custom Function Three (C.Fn3: Drive) in the custom functions menu tab and insure that under "Restrict Drive Modes" that there is a check mark next to the self timer setting you wish to use. If there is no check mark then that drive mode is disabled and not selectable using the AF-Drive button. It is on page 326 of the 1D X Instruction Manual.
