Speedlite 270EX II and Speedlite 320EX
Wireless E-TTL Compatibility
Wireless Control
The 270EX II and 320EX Speedlites make wireless flash photography available at entry-level prices for the first time. The controls and available settings of both Speedlites are designed to ease users' introduction to wireless flash, and encourage experimentation when users feel comfortable using an external flash.

Users can transform their pictures by finely controlling the angle and distance to subject of light sources. The best way to do this is by using external, wirelessly controlled flashes. The 270EX II and 320EX can both be set as wireless “Slave” flashes that can be remotely triggered by various methods, using any Canon EOS
SLR camera.

Triggering one (or more) off-camera 270EX II or 320EX flashes, set to their
“slave” mode:

Use the EOS 60D's Built-in Flash as a Master Flash
  • The integrated Speedlite transmitter in the Canon Rebel T3i, Canon EOS 60D or Canon EOS 7D (via built-in flash)
Optional Canon Speedlite Transmitter ST-E2 Mounted on the EOS 5D Mark II as a
Master Flash
  • Canon’s optional Speedlite Transmitter ST-E2 (mounted on-camera)
EOS 7D with Speedlite 580EX II set to "Master Flash" Mode
  • A Canon Speedlite 580EX II (or older
    580EX; 550EX model flashes) set to “master flash” mode
However, neither the 270EX II or 320EX have a “master” setting — they can NOT be used on-camera to trigger other flash units

Speedlite 320EX

Group Settings with Wireless
E-TTL Flash
  • The Speedlite 270EX II can be freely combined with other Speedlite units, but is ALWAYS set as a member of “Group A.”
    • The 270EX II also has no independent channels; this combined with the above means that the 270EX II will ALWAYS be triggered by any EOS compatible “master” unit, important to remember when working with multiple flashes or in situations involving other photographers.
  • The 320EX can be set to belong to group A, B or C. This allows it to be used off-camera alone, or with other EOS speedlites. Used in tandem with other slave units, full control of lighting ratios is possible between A:B or A:B C groups. And, it's fully compatible with the Rebel T3i's new "EasyWireless" mode � the easiest set-up for Wireless E-TTL ever.
