I thought I read somewhere that you can trigger the shutter remotely with the new 600EX/STE3 combo. For instance, with the ST-E3 mounted on the body, I believe you can trigger the shutter on the camera via radio with a 600EX. Can anyone confirm or refute this? I really like the Odins, but this feature would be a nice perk.
Actually don't have the STE3, but I have tried this with multiple 600EX-RT units, it works very well. Not only does the trigger work consistently at a very distant range but the slave unit you are triggering from can also flash for the exposure if it's part of the groups you have configured to fire.
One question that I had that I wanted someone with an STE3 to confirm is, can you really set second curtain sync on a remote flash triggered from the STE3 or is that incorrect in the documentation?
