Canon 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.

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.
  • 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.

CA Proposition 65

Attention to all California residents, Proposition 65 or officially known as, the Safe Drinking Water and Toxic Enforcement Act of 1986, is a law that requires warnings be provided to California consumers when they might be exposed to chemicals identified by California as causing cancer or reproductive toxicity. The warnings are intended to help California consumers make informed decisions about their exposures to these chemicals from the products they use. The California Office of Environmental Health Hazard Assessment (OEHHA) administers the Proposition 65 program and publishes the listed chemicals, which includes more than 850 chemicals. August 2016, OEHHA adopted new regulations, to go into effect on August 30, 2018, which changes the information that is required in or on Proposition 65 warnings.

We want you to know and be aware of our product safety and Midwest Photo is taking all of the necessary steps to comply with the applicable safety and health requirements made by this Proposition 65.

WARNING: This product may contain chemicals known to the State of California to cause cancer and birth defects or other reproductive harm.

This disclaimer can be found on the product pages on our website under the Additional Information tab which appears below the product description.
