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.

  • High-Speed sync

    Sync the flash at shutter speeds faster than the maximum sync speed of the camera by using high-speed sync flash. This allows you to still shoot at wide-apertures in bright daylight and so make use of faster prime lenses.

  • Control range

    For inside working, the ST-E2 provides a working range of between 12m and 15m. For outside working the range is between 8m and 10m.

  • AF Assist beam

    When shooting in low light conditions, the ST-E2 can emit a focusing beam to ensure sharp results. This beam aids focusing and covers all focusing points on all EOS cameras.
