Canon SPEEDLITE 220EX Mode D'emploi page 3

Thank you for purchasing a Canon product.
The Canon Speedlite 220EX is a compact flash unit automatically
compatible with E-TTL II, E-TTL, and TTL autoflash.
Read this instruction manual while also referring to your
camera's instruction manual.
Before using the Speedlite, read this instruction manual and your camera's
instruction manual to familiarize yourself with the Speedlite operations.
The basic operation is as easy as with normal AE shooting.
When the 220EX is attached to an EOS camera, almost all automatic
exposure control for flash photography is handled by the camera.
Although the 220EX is an external flash unit, it works automatically and
seamlessly just like the camera's built-in flash.
It is automatically compatible with the camera's flash metering
mode (E-TTL ll, E-TTL, or TTL).
The camera controls the Speedlite 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 Speedlite with a
Type-A camera.
For Type-B cameras, see page 4.
