Multi-Speedlite System By using multiple Speedlites, you can create more sophisticated lighting effects. The subject's face can look more three-dimensional or an accent light can be created. The flash exposure is fully automatic even with multiple Speedlites, making it very easy. The multi-Speedlite system can be wireless or wired. In a wireless flash system, a Type-A camera is attached with a master unit (550EX, ST-E2, or MR-14EX) and the 420EX is set as a slave unit. In a wired flash system, multiple EOS-dedicated Speedlites (including the 420EX) are connected by wired flash system accessories. Wireless Flash System The 420EX has a wireless slave setting that enables it to be a wireless slave unit. It can thereby be used in an E-TTL wireless autoflash system together with a Type-A (E-TTL-compatible) camera and a master unit (550EX, ST-E2, or MR-14EX). The flash exposure is controlled by the master unit which makes it easy to use a wireless flash system for sophisticated lighting effects. Using multiple Speedlites is as easy as using just one Speedlite mounted on the camera. For details on wireless flash photography or on master unit operations, refer to the master unit's instruction booklet. 0 OFF I_ SLAVE Set the master unit. • Attach the 550EX, ST-E2, or MR- 14EX to the camera and set it as the master unit.

Multi-Speedlite
System
By
using
multiple
Speedlites,
you
can
create
more
sophisticated
lighting
effects.
The
subject's
face
can
look
more
three-dimensional
or
an
accent
light
can
be
created.
The
flash
exposure
is
fully
automatic
even
with
multiple
Speedlites,
making
it
very
easy.
The
multi-Speedlite
system
can
be
wireless
or
wired.
In
a
wireless
flash
system,
a
Type
-A
camera
is
attached
with
a
master
unit
(550EX,
ST
-E2,
or
MR-14EX)
and
the
420EX
is
set
as
a
slave
unit.
In
a
wired
flash
system,
multiple
EOS-dedicated
Speedlites
(including
the
420EX)
are
connected
by
wired
flash
system
accessories.
Wireless
Flash
System
The
420EX
has
a
wireless
slave
setting
that
enables
it
to
be
a
wireless
slave
unit.
It
can
thereby
be
used
in
an
E-TTL
wireless
autoflash
system
together
with
a
Type
-A
(E-TTL-compatible)
camera
and
a
master
unit
(550EX,
ST
-E2,
or
MR-14EX).
The
flash
exposure
is
controlled
by
the
master
unit
which
makes
it
easy
to
use
a
wireless
flash
system
for
sophisticated
lighting
effects.
Using
multiple
Speedlites
is
as
easy
as
using
just
one
Speedlite
mounted
on
the
camera.
For
details
on
wireless
flash
photography
or
on
master
unit
operations,
refer
to
the
master
