As the title states...just got a mk 4 and the focus beam from the flash is not firing. It does fire on my 6d's. I did check the menu and "focus assist is enabled". What can I do next. I also check flash custom functions and they are in line.

Are you in single shot AF mode?

As Mike said, make sure you are not in servo mode.

A big downside of the 430ex III RT is that the flash will only emit one AF assist beam. The AF beam will not emit if any other AF point, other than the center AF point, is manually selected. The AF beam will also not work if in Liveview or if a color filter is used on the flash head. Look at page 87 of the manual.

Hope this helps.
