Product Details

Canon Speedlite Transmitter ST-E3-RT, Model 5743B002

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.

Features:

  • 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 mounted 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
    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 mounting foot creates a dust and water resistant seal between camera and flash.

      Great radio, when there's ambient light

        Comments about Canon Speedlite Transmitter ST-E3-RT:

        I used the ST-E3-RT with 3 600EX-RT flashes for a wedding reception and loved the ease of the system and the results -- that is, when I could focus. There is no focus assist beam when the radio trigger is on-camera, so as soon as it gets dark, focus performance diminishes significantly. You then have to mount one of the flashes on-camera to get improved focus, which defeats the whole purpose of off camera flash. So, the radio system works best when you're trying to create some fill in good-to-average light situations. Once it gets dark and you want to use the system to create off camera light, you're out of luck.

            Comments about Canon Speedlite Transmitter ST-E3-RT:

            This is a product I have wanted for a long time, and it works very well, but...... It should articulate like the flashes do, meaning go from the flat position that is currently to a screen up, vertical position so it can be read when the camera is at an eye level position on a tripod. I would like to see this change made in a new product. Very frustrating to have to either remove it from camera or remove whole camera from tripod to change settings, or carry a small ladder to be able to see the screen while it is mounted to a tripod. Just my 2 cents. I own a lot of canon gear including four (4) 600 ex rt speedlights which I love. Make this product go from good to GREAT! You can do it.....

            Where's the AF assist beam?

              Comments about Canon Speedlite Transmitter ST-E3-RT:

              Everything works great except No AF Assist Beam. Need that beam, put that in asap. The main flash 600EX-RT must be mounted on the camera at all time at night time, so what's the point of buying this ST-E3-RT then?

                  Comments about Canon Speedlite Transmitter ST-E3-RT:

                  Also have a single 600 flash. Wish they had an adaptor for my 580 flash. But great for getting rid of the cord for macro, hand pointing the flash, remote location of flash. I will be adding at least 1 more 600 flash to the arsenal.

                    Comments about Canon Speedlite Transmitter ST-E3-RT:

                    Canon had a winner with the older ST-E2 but is a bit short with the new radio transmitter ST-E2-RT. The omission of the focus assist light is major. My Canon 5D Mark II and Mark III cameras can focus well in daylight, but a dark room it is a challenge. The cameras just miss too much without a focus assist light. Canon omitted this feature and any other maker of radio transmitters also has no assist. So Canon has a great radio tool that may not deliver focus. As well it would have been better if we could integrate the ST-E3-RT with existing radio products. We have owned other radios for over 15 years. Some older receivers are built in our studio strobes. But the Canon will not talk to the current studio equipment. It is unfortunate that the Canon product has been priced at level higher than we've paid for radios with no cross communication. And no focus assist at this escalated price. Canon acts like they invented radio transmitting, but really we've been fighting line of site for a decade. We bought the new 600 flash system, but it really talks about Canon not understanding the studio photographer's big picture.

                      Comments about Canon Speedlite Transmitter ST-E3-RT:

                      Right out of the box, it performed exceptionally well. This is a long over due product that filled a gap that was provided by third party manufacturers, that tried to please everyone. This transmitter excels in the following points: 1-Controls the speedlites in both ETTL and M modes. 2-Controlls multiple flash groups, which opens the possibilities to infinite amount of combinations. 3-Eliminates the need to touch the remote flashes. 4-The most amazing mode of all is the stroboscopic, with multiple flashes on different group ratios. 5-Easy menu, with beautifully back-lit multi-function LCD, is located right on the top. The Only Drawback is: It doesn't have built-in HOTSHOE! that was a mini blunder! but i could live with that. Enjoy shooting, and shoot hard!
