Canon ST-E2 Speedlite IR Transmitter

The ST-E2 sets and controls all functions of its slave units. The flash output ratio between groups A and B can also be adjusted from 8:1 to 1:1 or from 1:1 to 1:8.

Under low-light or low-contrast conditions it emits an AF-assist beam linked to the camera's focusing points.

Note: 420EX/430EX cannot be used as the master slave to trigger other flashes.
