Other Precautions and Notes The wide attachment may obstruct the remote sensor (the range of the wireless controller narrows), or may cause a shadow to appear on the picture when recording with the assist lamp. The wireless controller may not work properly when the remote sensor is subjected to strong light sources or direct sunlight. If the wireless controller does not work, check if the remote sensor is set to [OFF].
Using the Flash The camcorder does not support the Bounce Flash function or the Wireless Multiple Flash System function of the Speedlite 420EX/430EX/550EX/580EX flashes. The camcorder does not support the ST-E2 Wireless Speedlite Flash Transmitter or the Wireless Sender/Receiver Control function of the Speedlite 420EX/430EX/550EX/580EX flashes. When recording under very dark conditions, as you keep the PHOTO button pressed halfway the AF assist lamp of the Speedlite flash may light on (if recording with autofocus).
Attaching the Adapter Holder Attach the adapter holder to use the optional CH- 910 Dual Battery Charger/Holder or a commercially available wireless microphone receiver.
