Is this trigger compatible with the Sony a6400?
Asked by: Krystle
Krystle, While the a6400 is not listed as compatible and had not been tested for complete compatibility in HSS and TTL, you can expect all normal synchronization and remote Manual power adjustments to work with this camera. The trigger does provide compatibility with nearly every currently available Sony camera that it has been tested with to date using the latest firmware.

Assuming that it has PC cord output, can it handle a 250V sync voltage as on a Vivitar 283 flash?
Asked by: L
The Westcott FJ-X3 S Wireless Flash Trigger for Sony Cameras is a transmitter only for a camera's hot shoe. The port on it is for charging, and it does not work as a receiver for flashes. There is a manual receiver available, but it cannot handle 250V.
