Thank you for purchasing a Canon product.
The Canon Speedlite Transmitter ST-E2 is a wireless transmitter for
controlling up to two flash slave groups consisting of Canon Speedlites
compatible with wireless flash shooting.
Also refer to the instruction manual of your camera and
Speedlite.
Before using the ST-E2, read this instruction manual and the instruction
manuals for your camera and Speedlite. Familiarize yourself with the operation
of each before using the ST-E2.
It is automatically compatible with the camera’s flash metering
mode (E-TTL ll, E-TTL, or TTL).
The camera controls the ST-E2 automatically in the following flash metering
modes:
1. E-TTL II autoflash (evaluative flash metering with preflash reading/lens
distance information)
2. E-TTL autoflash (evaluative flash metering with preflash reading)
3. TTL autoflash (off-the-film metering for real-time flash metering)
Regarding the camera’s available flash metering modes, refer to the
“External Speedlite” specification in the “Specifications” of your
camera’s instruction manual.
The camera instruction manual’s chapter on flash photography will refer
to cameras having 1 and 2 above as a Type-A camera (compatible
with E-TTL II or E-TTL). And cameras having 3 (compatible with only
with TTL) are called Type-B cameras.
* This instruction manual assumes that you are using the ST-E2 with a Type-
A camera.
If the ST-E2 is used with a Type-B camera, only manual flash shooting and
stroboscopic flash will be possible.
