ST-E2
For any photographer wanting to use remote flash with Canon flashguns, the ST-E2 is an invaluable accessory. It attaches to the hotshoe of the camera and acts as a master unit to control, via infra-red, up to two groups of remote EX-series Speedlite flashguns.
It provides full ETTL or ETTL-II flash control and control of lighting ratios between the two flash groups for more complex flash setups. It also allows for high-speed sync flash.
The ST-E2 is also invaluable for shooting in low-light conditions. It projects an AF assist beam pattern onto the subject to aid autofocusing in the dark.
