The Canon ST-E10 Speedlite Transmitter for EOS R3 draws its power supply from your camera, making it smaller and lighter in weight compared to battery powered transmitters.

Key Features:

New Multi-Shoe Connection

The ST-E10 speedlite transmitter is equipped a new 21 pin multi-accessory shoe connection, which suits the R3.

Compact, Battery-Free Design

Compact in size, the ST-E10 does not have an LCD screen or use batteries. All power is sourced through the camera, and all settings can be adjusted on the camera screen with ease.

Set Through Camera or Smatphone

You can adjust settings of multiple flash units through the camera, or connect your smartphone with the Canon Camera Connect app.

Reliable and Fast Transmission

The ST-E10 speedlite transmitter takes advantage of radio transmission, making it less susceptible to interference from obstacles at up to 30m away.

Dust and Drop Proof

The ST-E10 speedlite transmitter is dust and drip proof, making it a great addition to Canon's already rugged cameras and accessories.

Smart Power Saving

The transmitter has a smart power saving where if there is no usage for 5 minutes, power will automatically turn off so your battery power can be saved.
