I have an odd problem.
I set hi-speed sync today but when I went to use it had gone back to standard sync mode and now I cannot set Hi-Speed sync at all.
Normally you press the +&- buttons together to around different sync modes; First-Curtain, Hi-speed, Second-Curtain.
Now it just cycles between First-Curtain and Second-Curtain.
Any one had this issue or any ideas?
