Autoflash with One Receiver

This section describes basic fully automatic wireless shooting with an EL-1 (Ver.2) attached to the camera as a sender and an EL-1 (Ver.2) set as a receiver.

  1. Set up a unit as the sender.

    • Set the EL-1 (Ver.2) attached to the camera as a sender ().
    • Devices equipped with the optical transmission wireless sender function can also be used as a sender unit.

  2. Set up a unit as the receiver.

    • Set the EL-1 (Ver.2) for wireless control by the sender as the receiver ().
    • You can also use other EX-series Speedlites that are equipped with an optical transmission wireless receiver function.
    • You can use any of A, B, or C as the firing group (1).

  3. Check the channel.

    • If the communication channels of the sender and receiver units are different, set them to the same channel ().

  4. Position the camera and other Speedlite.

  5. Use the joystick on the sender to select MODE.

  6. Set the flash mode to ETTL.

    • Press the joystick vertically or horizontally or turn Select dial to select ETTL, then push the joystick straight in.
    • The receiver is automatically set to ETTL during shooting, as controlled by the sender.
    • Confirm that firing group control is set to ALL.

  7. Confirm that flash recharging is finished.

    • When the receiver flash is ready, the AF-assist beam emitter blinks at approx. 1-second intervals.
    • Check that the sender unit's flash-ready lamp is lit.

  8. Check operation.

    • Press the sender unit's test flash button.
    • The Speedlites fire. If it does not fire, check that it is placed within the transmission range ().

  9. Take the picture.

    • Just as in normal flash photography, shoot after configuring the camera.

Caution

  • If there is a fluorescent light or computer monitor near a receiver unit, the presence of the light source may cause the receiver unit to malfunction and fire inadvertently.
  • During optical transmission wireless shooting, even if the sender and receiver units (firing group) are not all fully charged, CHARGE will not be displayed on the sender unit's LCD panel as it is with radio transmission wireless shooting (with sender flash firing OFF). Also, there is no function for illuminating or turning off the sender unit's LCD panel according to the charge status of the sender unit and receiver units.
  • When P.Fn-06-0 is set on the sender unit (), the beep will sound when the sender unit is fully charged (This beep does not indicate that charging of all flash units is completed as it does with radio transmission wireless shooting).

Note

  • Flash coverage of the sender and receiver is set to 24 mm. You can also set the flash coverage manually.
  • The sender can also fire ().
  • You can fire the modeling flash by pressing the camera's depth-of-field preview button ().
  • To turn on a receiver that is in auto power off mode, press the sender test flash button.
  • Test flash firing is not available while a camera's flash timer or similar functions are active.
  • You can change the time until auto power off takes effect on a receiver in C.Fn-10.
  • You can disable the blinking of the AF-assistant beam emitter when the receiver unit is fully charged (C.Fn-23).

Autoflash Photography Using Multiple Receiver Units

When you need more flash output or you want to perform lighting more easily, you can increase the number of receiver units and fire them as a single flash.

Add a receiver, and follow the same procedure listed in “Autoflash with One Receiver” (). You can use any of A, B, or C as the firing group.

When the number of receiver units is increased or sender flash firing is set to ON, automatic control is performed to fire all flashes at the same flash output and to ensure that the total flash output results in the standard exposure.

Flash Photography Applying Wireless Features

The wireless system eliminates the need to set up the following features on receivers, which are automatically configured based on sender settings. This enables wireless flash photography much like normal flash photography.

Caution

  • The flash frequency when performing stroboscopic flash during optical transmission wireless shooting can be set from 1 Hz to 199 Hz (settings from 250 Hz to 500 Hz are not available).

Note

  • You can also set flash exposure compensation and flash coverage manually on each receiver.

Using Multiple Senders

Multiple devices can be set as senders. Wireless flash photography under the same lighting arrangement (with the same receivers) is also possible using other cameras, by switching the camera that the sender is attached to.
