Canon ST-E2 Transmitter Description


The Canon ST-E2 Speedlite Transmitter unit is a wireless autoflash transmitter that can control up to two Speedlite 550EX groups set as slaves. The transmitting range available on the ST-E2 is approximately 15 meters indoors, and 10 meters outdoors. The operations that can be transmitted through wireless control are E-TTL autoflash, High-speed sync, FE lock, Flash Exposure Compensation, Manual flash, and multi-flash firing. 

The Speedlite ST-E2 Transmitter can now be used as your on-camera master unit instead of a 550EX or MR-14EX. This allows an unlimited number of Speedlite 420EX and/or 550EX slave units to achieve precise main, fill and background lighting. The ST-E2 Speedlite ST-E2 Transmitter operates at up to 33' outdoors and up to 49' indoors without cumbersome wires. It also permits E-TTL flash with ratio control of two groups of slave units controllable over a six-stop range.
