I am looking (not finding) a firmware update for the ST-E3-RT controller. My hope is that Canon has allowed the controller to use the 600 RT flash in 2nd curtain sync. I would think that for 1000.00 dollars US you would be able to have some creative capabilities with the system.
Is it possible to use 2nd curtain sync using the ST-E3-RT controller with the 600RT flashes?
I cant find any way to access the feature other than having the flash on the camera body.
