Please resolve the conflicting answers about Canon ST-E3-RT compatibility: One staff answer says YES ST-E3-RT will trigger the FJ400. But another answer says NO, Westcott has now disabled this compatibility. So which is it?
Asked by: Eric
Westcott has not disabled this compatibility. The ST-E3-RT DOES in face operate the FJ400 Strobe. It is done simply by matching groups, channels, and ID number of the ST-E3-RT and that of the FJ400.

Can you run this off AC power without the battery attached?
Asked by: Elizabeth
No, the AC power input is on the back of the battery. This allows you to charge the battery while shooting, so that you have a full battery when you want to be more portable.
