Camera Trigger SYNC mode syncs the shutter trigger time to the Flash trigger time. This allows you to concentrate on the Flash rather than the camera, there are a couple of things you need to know though. See the guide at https://www.dropcontroller.com/camera-trigger-sync-mode/

There's always one!
Did a workshop yesterday, one of the group found a bug with the Camera Trigger time. Apparently if you use SYNC mode and very large (very very large) offset time you set the camera trigger pulse time to zero. Who knew!

Anyway, fixed now. New firmware available for dropControllerV4 and dropControllerV4 mkII. See the download page at

dropControllerV4. New firmware update.

Firmware DC4_606 adds a valve drain time out and fixes an obscure issue in BULB mode.

Some valves can become hot when left open for extended periods of time. The new valve drain time out helps prevent this.

BULB mode got upset when using a very large offset time. I'm not sure why you'd want to use a large offset with BULB but now you can 😀
