Hi All, I’m having a problem with syncing my Canon 80D to my Alien Bee B800. I have the AB standard 15-foot sync cord going from the 80D (with a hot shoe adapter mounted) directly to the B800. One night all was well but the next night the unit failed to flash. I switched out the B800 with a 2nd unit and also used both a different sync cord and hot shoe adapter to no avail. I know the flash is not defective because I can manually release it using the flash test button. I made sure all connections were firm. Could it be that somewhere in the process I inadvertently disabled something in the 80D’s menu system? Any suggestions? Thanks in advance.
