ProMaster ST1C TTL Speedlight Transceiver for Canon

New from ProMaster the ST1 series Speedlight Transceiver units that allows you to use your TTL off-camera flash unit whether they are Canon (like a 430, 580, or 600 series Canon flash) or ProMaster Speedlight (like the 100SL or 200SL Speedlights). The ST1C can also be used to trigger your camera itself for remote triggering using the 2.4GHz signal (with additional cable to turn into a wireless shutter release).
