So, with my Yongnuo YN-622 receiver I just run the sync cable from the shoemount trigger to my AB1600 directly (not wirelessly) and I can sync upwards of 1/2000 with my 6D. Tried this with my A6000 and nothing. Major suckage as I really want to dump my Canon stuff and go all-in Sony. With the 6D I just enable HSS, but I don't see any option for this in my A6000. Am I missing something? Thanks a lot!
