More details on the Canon ST-E10
Overview: The Canon Speedlite Transmitter ST-E10 works with Canon cameras equipped with the Multi-Function Shoe and supports wireless flash shooting. Up to 15 total flash units in 5 groups can be controlled with the transmitter. The camera provides the power through the Multi-Function Shoe, eliminating the need for batteries in the transmitter. Because there are no batteries, the ST-E10 is approximately 30% smaller and approximately 50% lighter than the ST-E3-RT II transmitter. Dimensions: W-1.79", H-1.49", D-2.11"; Weight: 1.7 ounces.
Compatibility: The ST-E10 only works with cameras with the Multi-Function Shoe, such as the Canon EOS R3. It is compatible with Canon Speedlites that support wireless multiple-flash photography using radio transmission, including the EL-1, 600EX II-RT, 600EX-RT, and 430EX III-RT.
Multi-Function Shoe: Canon's new Multi-Function Shoe provides power and advanced communications to its compatible accessories. In addition to the Speedlite Transmitter ST-E10, other Multi-Function Shoe-compatible attachments include the Stereo Microphone DM-E1D, and the Smartphone Link Adapter AD-P1 for Android (coming early-to-mid 2022). Because of the Multi-Function Shoe's connection between the camera and transmitter, you can view and configure the transmitter's features and settings through the camera's menu.
Wireless Flash Photography: Shooting with multiple flash units can be achieved using the ST-E10 wireless transmitter (sender) and compatible Canon Speedlites that support radio transmission wireless shooting (receivers). The ST-E10 can transmit the 2.4GHz radio signals approximately 98.4 feet (30 meters). The transmission distance may be shorter depending upon conditions, such as the positioning of the flash units, the surrounding environment, and the weather. You can shoot in up to 5 different groups, and a total of 15 flash units. Other flash settings include Flash Exposure Compensation (±3 stops in 1/3 or 1/2 stop increments), Flash Exposure Bracketing (±3 stops in 1/3 or 1/2 stop increments), High-speed Synchronization, and Second-curtain Synchronization. You can manually vary the flash output from 1/1 to 1/8192 (1/3-stop increments).
Transmission Channels: To avoid interference with other photographers' wireless systems with multiple radio-controlled flash units, you can change the transmission channel and wireless radio ID. The transmission channels can be set manually or automatically to channels 1 through 15. If setting a 4-digit transmission ID, it can be done manually from 0000 to 9999.
Auto Power Off: The ST-E10 is powered by the camera through the multi-function shoe. Since the transmitter has no power switch, it will turn on and off as you power up/down the camera. The ST-E10 will automatically turn off 5 minutes after the camera's auto power off feature is activated, if no operation is performed. The transmitter will awaken when the camera is awakened, or when the unit's Menu button is pressed. Until the ST-E10 turns off automatically, it will continue to consume camera battery power.
Canon's Camera Connect App: With the Canon Camera Connect App, you can conveniently change the flash settings on your smartphone or tablet. Using tap and swipe actions, you can view and configure the camera's flash settings on your smartphone. Your smartphone must be connected to the camera via Wi-Fi or Bluetooth to change the settings. The Camera Connect app is compatible with Apple iPhone, iPad, and iPod touch running iOS 14.0 or later, and with Android devices (the version varies with the device).
