Speedlite Transmitter ST-E10

The radio-enabled Speedlite Transmitter ST-E10 utilizes the new Multi-Function Shoe and inherits most of the features from the Speedlite Transmitter ST-E3-RT. With a minimalist and battery-less design, the ST-E10 eliminates the need for batteries and display panel, allowing an ultra-compact form factor.

  • Wireless flash control via camera & smartphone
  • No battery required
  • Compact & lightweight

Compact & Lightweight

The Speedlite Transmitter ST-E10 works on cameras that sport the new Multi-Function Shoe. With the ability to draw power supply directly from the camera, there is no need to worry about changing batteries during a photo shoot. This is where convenience meets compactness.

In addition, flash settings can be adjusted on the camera menu, or you can do so remotely via the Canon Camera Connect smartphone app.

Wireless Control

There are two LEDs and one Menu button on the back of the Speedlite Transmitter ST-E10. The LEDs indicate the connection with other Speedlites and whether the Speedlites are ready to fire.

The Menu button functions as a shortcut button to access the flash settings on the camera display. 

Use the Camera Connect App to remotely control the flash settings for greater convenience.

Radio Transmission

Speedlite Transmitter ST-E10 can reach up to 30metre transmission range. It is not affected by environment lighting and does not require direct line-of-sight, allowing for better creative freedom and reliablity.

  • 5 groups of flash

  • 15 channels
