The Phottix Aion is a wireless trigger that makes it easy to create a unique lighting effect with your wireless flash units. This trigger uses the 2.4 GHz radio system for operating flash devices within the range of 60 m. With this trigger, you can release the shutter, set number of frames to be captured, and set the auto-bracketing timer for HDR photos. The trigger also allows you to use the AF and shutter release individually. With this trigger, you can set the flash to synchronize with the camera to take five continuous shots with a 2-second delay. The trigger has a standby battery life of 48 hours.
