Canon SPEEDLITE 430EX Manual De Instrucciones página 3

Thank you for purchasing a Canon product.
The Canon Speedlite 430EX is a multi-feature flash unit for Canon EOS
cameras. It works automatically with E-TTL II, E-TTL, and TTL
autoflash systems. It can be used as an on-camera flash or as part of a
wireless flash system.
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 familairize yourself with the Speedlite operations.
The basic operation is the same as with normal AE shooting.
When the 430EX is attached to an EOS camera, almost all automatic
exposure control for flash photography is handled by the camera.
Although the 430EX is an external flash unit, it works automatically and
seamlessly like the camera's built-in flash.
It is automatically compatible with the camera's flash metering
mode (E-TTL ll, E-TTL, and 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 Speedlite's major specifications are
listed in "External Flash Items."
The camera instruction manual's chapter on flash photography will refer
to cameras having 1 and 2 as a Type-A camera (compatible with E-
TTL II or E-TTL). And cameras having 3 (compatible with only TTL) are
called Type-B cameras.
* This instruction manual assume that you are using the 430EX with a Type-A
camera.
For Type-B cameras, see page 35.
