Sony A1 Rear sync settings

[DKW]

Hi everyone. I can’t get rear sync to work on the A1. It flashes as normal, at the start. Flash works fine with triggers but not for this. Any help would be gratefully received.

I have tried on elinchrome and profoto powered and battery.

It works with by A91 simply by changing the menu item to rear sync. Frustrating….

Thank you. David

Just a guess - have you tried switching to mechanical shutter?

Thank you for the suggestion. I had missed a firmware update and once uploaded, it worked.
