Speedlite Transmitter ST-E3-RT
------------------------------
For sophisticated wireless flash setups, there's nothing like the
new Speedlite Transmitter ST-E3-RT*. Facilitating radio
controlled, two-way wireless transmission up to 98.4 feet, among
up to five groups or fifteen individual Speedlites, the ST-E3-RT
represents the next generation in wireless flash systems. With
operational controls similar to the new Speedlite 600EX-RT,
including diverse flash metering options, and a number of flash
modes, the Speedlite Transmitter ST-E3-RT makes complex lighting
setups simple. With a compact design and highly reliable
construction, combined with a clearly laid-out information panel
and buttons with back lighting and more, the Speedlite
Transmitter ST-E3-RT is an indispensible tool for advanced,
professional flash photography.
*Because it does not have an optical transmission function, the
Speedlite Transmitter ST-E3-RT is not compatible with earlier
Speedlite models such as 580EX II.
Newly designed wireless system uses 2-way radio wave
communication for enhanced communication among master and slave
units. Achieves a transmission distance of up to 98.4 ft./30 m,
all at a 360 degree angle.
-----------------------------------------------------------------
The Speedlite Transmitter ST-E3-RT facilitates radio controlled,
two-way wireless transmission up to 98.4 feet, for a reliable and
robust connection among master and slave units. Communicating on
2.4 GHz frequencies, the Speedlite Transmitter ST-E3-RT does not
have the same directional limitations of traditional wireless
optical transmitters. Where other wireless signals can be
interrupted by physical obstacles, radio controlled systems
excel. Fifteen transmission channels are available, selectable
manually or automatically, and radio transmission IDs can be set
to prevent misfiring in the event of signal interference on the
same channel. With the extended, more reliable range afforded by
radio transmission, ambitious photography is made easier.
Up to 5 groups, or 15 individual flashes can be controlled via 1
transmitter.
-----------------------------------------------------------------
With the Speedlite Transmitter ST-E3-RT, up to fifteen flashes in
five groups can be controlled via a single unit. Each group can
be set to a different flash mode, enabling multiple
configurations for creative photography. For example, with the
Speedlite Transmitter ST-E3-RT, some flashes can be directed to
operate according to the cameras meter reading, others can be set
manually; groups can be set to overexposure or underexpose, and
much, much more. With up to fifteen flashes under the control of
one transmitter, wirelessly, complex lighting setups normally
reserved for the studio are a breeze.
Supports E-TTL II flash, manual flash, stroboscopic and auto
external flash metering.
-----------------------------------------------------------------
For any number of shooting styles, the Speedlite Transmitter
ST-E3-RT supports E-TTL II flash metering, manual flash (1/1 to
1/128) and stroboscopic flash (1/4 to 1/128, 1 to 500 Hz). Auto
external flash metering is even possible when the Speedlite
Transmitter ST-E3-RT is ed to the EOS-1D X or the EOS 5D
Mark III.
Dot matrix LCD panel displays all pertinent information
simultaneously and backlit control panel means easy operation.
-----------------------------------------------------------------
The Speedlite Transmitter ST-E3-RT features an all-new dot matrix
LCD panel (172 x 104 dots). This new LCD displays Flash status,
flash settings and wireless configuration with more detailed
information in comparison to previous systems. With its new
screen combined with backlit operation buttons and even an
internal sound emitter, the Speedlite Transmitter ST-E3-RT is as
easy to operate in the dark as in daylight.
8 types of custom functions, 3 types of personal functions.
-----------------------------------------------------------
To accommodate the demands of a number of different shooting
situations, the Speedlite Transmitter ST-E3-RT can be configured
with eight types of custom and three types of personal functions.
Custom functions include: auto power off, modeling flash
controls, sound, illumination and more. Personal functions
include display contrast and LCD panel illumination color for
both master and slave flashes.
Improved hot shoe contacts for more reliable information
transmission and operation; compact design is approx. 2.65 (w) x
2.42 (H) x 3.05 (D) in.
-----------------------------------------------------------------
The Speedlite Transmitter ST-E3-RT is built to the standards one
would expect from professional Canon camera systems. A newly
updated hot shoe contact ensures reliable communication between
camera and transmitter. Dust and water resistance is excellent as
well: all moving parts and areas surrounding the transmitters
display and buttons are sealed for uninterrupted performance in
harsh conditions. A new dust and water resistant adapter for the
ing foot creates a dust and water resistant seal between
camera and flash. Compact and lightweight, the Speedlite
Transmitter ST-E3-RT is approx. 2.65 (w) x 2.42 (H) x 3.05 (D)
in.
