E-TTL/E-TTL II Wireless Autoflash Control
Up to three groups (for main, fill, and background)
of slave units can be set up for comprehensive
c
ontr
ol of flash lighting. The Speedlite slave units
can be assigned to group A, B, or C, with output
ratio between groups A and B adjustable from
8:1 to 1:1 or 1:1 to 1:8. The output of the group C
can be adjusted through flash exposure compen-
sation. You can concentrate on perfect lighting
because the E-TTL/E-TTL II autoflash system controls
the total flash output to ensure consistently correct
exposure. Also, when Speedlite 580EX II is used with
any current EOS Digital SLR and most EOS 35mm
cameras, you can fire a modeling (preview) flash
for a full second at 70Hz by pressing the depth-of-
field preview button. Even with multiple Speedlites,
the modeling flash fires according to the ratios
y
ou have set. E-TTL/E-TTL II wireless autoflash
also supports most other Speedlite features,
such as FE Lock, FP Flash, Flash Exposure Bracketing/
C
ompensation, and Stroboscopic Flash. Finally,
for macro shooting, the Macro Ring Lite MR-14EX
and Macro Twin Lite MT-24EX can be used as
m
aster units, as well.
Sample Photo Analysis – Three flash units provided illumi-
nation. The light from the master flash unit (A), a Speedlite

A slave 580EX II (B) was set far enough away on a desk to
be pointed directly at the statue, and another 580EX II (B)
was used to light up the overall office. Based on the results
disp
la
yed on the c

LCD monitor, the brightness of
the master flash unit was halved to achieve natural lighting.

Canon’s EX series Speedlites have made multiple-flash photography simple,
wireless and automatic. Using either the Speedlite 580EX II or the Speedlite
Transmitter ST-E2 as a master unit, wireless signals are transmitted to an unlimited
number of Speedlites 580EX II or 430EX II, creating myriad possibilities for
lighting, no matter the location.
