Wireless Flash Photography

Shooting with sophisticated wireless lighting from multiple flash units is as easy as normal E-TTL II/E-TTL autoflash shooting when you use the transmitter with a Canon Speedlite supporting radio transmission wireless shooting as the receiver.

The system is designed so that the settings of the transmitter (sender) attached to the camera are automatically applied to the wirelessly controlled Speedlite (receiver). This eliminates the need to operate receivers when shooting.

Positioning and Operation Range

  • Autoflash using one receiver ()

    (1) Receiver EL-1

    (2) Sender ST-E10

    (3) Transmission distance: Approx. 30 m / 98.4 ft.

  • Autoflash using groups of receivers ()

    E-TTL II / E-TTL autoflash photography is possible with two or three receiver groups, and the flash ratio (proportion of flash output) can be adjusted as needed. In addition, you can set and shoot in a different flash mode for each firing group, with up to five groups.

    (1) 2 groups (A, B)

    (2) 3 groups (A, B, C)

    Caution

    • Take a few test shots in advance.
    • The transmission distance may be shorter depending on conditions such as the positioning of the flash units, the surrounding environment, and the weather.

    Note

    • Set up receivers using the mini stand included with them.

  • Shooting in a different flash mode for each group ()

    This is only one example of flash mode settings.

    5 groups (A, B, C, D, E)

    (1) Auto external flash metering

    (2) E-TTL II

    (3) Manual flash

    (4) Manual flash

    (5) Manual flash
