E-TTL II
Canon E-TTL (Evaluative
Through-The-Lens) flash
exposure control uses a
preflash fired after the
shutter button has been
fully depressed — but
before the camera’s reflex
mirror goes up. The cam-
era’s Evaluative metering
sensor — the same sensor
that reads ambient light —
is used to compare the
ambient light values with
the light reflected from the
subject by the preflash.
The camera then calculates
and stores the flash output
required for optimum
exposure of the main sub-
ject and the background.
E-TTL II additionally incorporates distance information
from compatible EF lenses for the most precise flash expo-
sure control. For example, it ignores sensor areas that
report abnormally high levels, eliminating underexposure
that can otherwise be caused by straight reflections.
Correct flash exposure is ensured even when shooting a
subject with a highly reflective object in the background, or
if the subject itself is highly reflective. In addition,
because distance information is used in calculating the
flash output level, E-TTL II prevents over-exposure when
photographers lock focus and recompose.
Wireless Auto Flash
Control
Multiple Speedlites can
obtain lighting effects not
possible with a single
flash. While previous
multiple-flash setups
required cumbersome
wires to connect the camera and flashes, compatible
EOS Speedlites can be used as wireless Slaves. With a
Speedlite 580EX II or Speedlite Transmitter ST-E2 attached
to an EOS Digital SLR, an unlimited number of compatible
EX-Series Speedlites can operate as dedicated Slave
units. With nothing more than an EOS camera and a num-
ber of Speedlite flashes, the opportunities for creative
lighting are endless.
Macro Photography and Wireless Options
The Canon Speedlite flash system family includes versatile
solutions for macro photography requirements: The Macro
Ring Lite MR-14EX features twin circular flash tubes that
can be fired at equal or uneven power with a ratio that can
be varied over a six-stop range. One or more compatible
EX-Series Speedlites can be used as wireless slaves along
with the MR-14EX. Incandescent focusing lamps and two
types of modeling flash are provided to enable preview of
lighting effects. The controller unit features an illuminated
full-information LCD panel and accepts optional hi-capacity
battery packs.
The Macro Twin Lite MT-24EX gives serious close-up, nature
and macro enthusiasts a different, directional option in
macro lighting. The two separate flash heads can be
swiveled around the lens and aimed independently. They can
even be removed from their holder and mounted off-camera.
Flash head output can also be independently adjusted with
easy ratio control over a six-stop range. Like the MR-14EX,
the Macro Twin Lite MT-24EX is fully E-TTL compatible with
all EOS SLR bodies. Wireless E-TTL flash control is possible
with one or more 580EX II, 580EX, 550EX, 430EX II, 430EX,
or 420EX Speedlites configured as slave units.
The Speedlite Transmitter ST-E2 is a dedicated controller
that can be used with an unlimited number of compatible
Speedlite slave flashes. The transmitter is effective over
distances up to 33 ft. outdoors and 49.5 ft. indoors.
Integral to the EOS System, Canon Speedlites are the ideal flash
light source for EOS SLR cameras. They are technologically
advanced to provide perfect exposure and illumination with just
about any subject. They are also highly adaptable, providing
an endless variety of configurations and versatile shooting
options. For professional flash photography, rely on Canon
Speedlites to solve the most demanding lighting challenges.
