For Type-A Cameras

Basic Flash Photography

When the Speedlite 550EX is attached to a Type-A camera such as the EOS- 3, you can take flash pictures with E-TTL autoflash as easily as normal autoexposure (AE) pictures.

As with evaluative metering, the E-TTL autoflash system uses a multi-zone sensor. A preflash is fired for evaluative flash metering and the reading is stored in memory. Since E-TTL autoflash is linked to the active focusing point, the flash exposure is highly accurate. The result is a natural-looking flash picture with excellent balance between the flash light and ambient light.

•This section assumes that the Speedlite 550EX is used with a Type-A camera.

•Before proceeding, first turn on the EOS-3 and the 550EX.

•Set the 550EX’s wireless selector to OFF.

•For EOS-3 operations, refer to the EOS-3 Instructions.
