Canon Multi-Function Shoe Compatible. The Canon ST-E10 Speedlite Transmitter connects directly to select Canon cameras’ Multi-Function Shoes and is powered by the camera, which eliminates the need for batteries or cabled connections. This in turn helps to prevent interruptions and interference. The ST-E10 is currently only compatible with the Canon EOS R3.

Flexibility and Intuitive Design. The ST-E10 transmitter has a 98.4-foot range and can control up to five groups or fifteen individual flashes. It only features one on-board control: a menu button that opens a menu on the connected camera so that you can change settings and make adjustments.

Canon Camera Connect App. You can also adjust flash settings via a compatible mobile device that’s paired to the camera and running the Canon Camera Connect app.
