What's Included?

The Speedlite Transmitter ST-E3-RT (Ver.2) provides some much anticipated upgrades from professionals to make it an even more appealing resource for flash photography when used with the Speedlite EL-1. This updated version allows for wireless rear curtain synchronization to capture ambient light trails and convey a sense of speed for moving subjects. The expansive minimum output range (down to 1/8192 power) gives you increased opportunity for creativity over the flash output from brightest to dimmest. And you now have FE Memory as part of the radio transmitter, so you can lock-in an E-TTL flash exposure level, even in complex multi-flash set-ups, and continue to use it for the same scene or subject. These improvements combine with the previous benefits of its predecessor including radio controlled, two-way wireless transmission up to 98.4 ft., among up to five groups or fifteen individual Speedlites, a dot matrix LCD with backlighting, intuitive controls and more.

Disclaimer
*When used with the Speedlite EL-1 in combination with an EOS R5, EOS R6, EOS-1D X Mark III or EOS M50 Mark II camera. Some features will work with older Speedlite models such as 600EX II-RT, 600EX-RT and 430EX III-RT, and previous EOS cameras, but not all. As of February 3, 2021.
- Manual flash power below 1/128th not possible with 600EX-RT series, and 430EX-RT used as receiver units
- 2nd curtain sync can be used with Speedlite EL-1, 600EX-RT series and 430EX-RT receiver units, but with EOS R5, R6, or EOS-1D X Mark III cameras only
