HIGH SPEED SYNC
The ProMaster FL1 will allow the use of shutter speeds higher than your camera’s top flash sync speed in TTL mode by activating the High Speed Sync. This allows you to use shutter speeds as fast as 1/8000 second. The use of High Speed Sync is particularly useful when using large apertures in bright situations or freezing motion.
