E-TTL,

and

TTL

autoflash

.

It

can

be

used

in

three

different

wags

:

As

a

normal

on-camera

flash,

the

master

unit

for

a

wireless,

multi-Speedlite

flash

system,

or

a slave

.

attached

to

an

EMS

camera

;

almost

all

automatic

exposure

control

for

flash

photography

handled

by the

camera

.

It

is

almost

the

same

as

using

the

camera's

built-in

flash

if

it

has

one

.

Youcan

think

of

the

580EX

as a

built-in,

high-output

flash

.

It

is

automatically

compatible

with

the

camera's

flash

metering

mode

{E-TTL

II,

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

real-time

flash

metering)

Regarding

the

camera's

available

flash

metering

modes,

with

E-TTL

or

E-TTL

II)

.

And

cameras

having 3 (compatible

with

only

TTL)

are

called

Type-113

cameras

.

This

instruction

manual

assume

that

you

are

using the
