V6ii and Alien Bee above sync speed Pentax

Hi, all!
I'm so far unsuccessful. Anyone having success syncing v6ii with v6ii rx and alien b800 with sync cable above sync speed?
Thank you!


  • Sorry but you are out of luck, since even at full power the B800's flash duration is 1/3300s, way shorter than what would work - which has to be 1/100s or longer.
