1. Does the high speed synch only work on the hot-shoe, ie not wireless?
Not using the on camera flash as a commander. You can do it using a 550ex, 580ex, or 580sx II as a master or with the ST-E2.
...2. Is there a way to have the flash fire in the second curtain wirelessly?
...Only third party options for this. ...You can of course use a wired remote connection.
Looks like I still need to carry my Flash Zebra long ETTL cord. Drat!
I'm glad, though, that the menu system on the 7D grays out non-available functions; it's making the learning curve much easier for me.
