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 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
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
Up to 5 groups, or 15 individual flashes can be controlled via 1 transmitter
Supports E-TTL II flash, manual flash, stroboscopic and auto external flash metering
Dot matrix LCD panel displays all pertinent information simultaneously and backlit control panel means easy operation
8 types of custom functions, 3 types of personal functions
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.
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
