When the 420EX is mounted on a Type-

A camera such as the EOS 30/ELAN

7E, using E-TTL autofiash is just as

easy as normal autoexposure (AE).

E-TTL autoflash uses the camera's

multi-zone metering sensor for highly

precise flash exposure control. A

preflash is fired for evaluative fiash

metering and the reading is used to

determine the main flash output. The

result is a flash picture with excellent

balance between the flash illumination

and ambient light.
