The Promaster #4667 ST1C Wireless Transceiver for Canon speedlights. This unit is brand new never used and boxes were never even opened until I did so to prepare auction listing. I did not remove any of the original packaging. Just pulled out the contents to show that the item is brand new and has never been used.
TRANSCEIVER:
A ProMaster ST1 is a dedicated transceiver compatible with Nikon flash systems including the Nikon SB-500 and SB-910, and of course they work equally well with the ProMaster 200ST-R. With a range of 325 feet, they will allow synchronized triggering within a studio space, outdoors in the woods, or a place as massive as an auditorium.
TTL (through the lens) technology means the photographer can focus their attention on composition and subject matter rather than becoming distracted by needing to calculate proper exposure. These units integrate beautifully with all automatic settings of the speedlight they are using. This simplicity is retained regardless of the number of flashes they use. Yet they can create multiple firing groups or control the flash output ratios if that is what they want to do.
One feature not to overlook is that the ST1 can be used as a remote shutter release. Connect one to the camera using a camera release cable. Then, by using the little button on top of a second transceiver, you can trip the shutter on the camera!
