In a burst of mad enthusiasm I bought the Nisin air commander and receiver and I can use the Nissan air commander and the Air R receiver to trigger my studio flashes or any of the speed lights I own in manual mode regardless of brand. What will not work however, which is what I want, is to get the HSS working ,. It works in that I can dial in shutter speeds in excess of 1/250 and the flash does fire but it is not recorded I have tested at all power ranges from full to as low as can be set and two different brand of studio mono blocks , bowens, and cheap no name chinese brand. My yn560 flashes all work finat 1/250 or less but not above.as well. it obviously is a flash duration thing but I don't understand why, and yes I understand the sync speed limitations and the true hss gives multiple flashes, so I assume the flash duration on the flashes tested is just to short. If that's the case then I either need another light, just one to work outdoors, or they go back to Amazon.
