Detailed Features

E-TTL II flash control
Working with the E-TTL II flash metering system, the ST-E2 ensures wireless flash exposures are accurate and consistent in all situations. In complex lighting conditions make use of exposure compensation for more control of light output.

Ratio control
Control the ratio of light output of two groups of flashes for creative results by using the ratio control available on the ST-E2. Controlling the ratio between 1:8 and 8:1 for the two groups of Speedlites provides a wide range of adjustment.
