Default Question to 7D users (Wireless flash)

Can the 7D's wireless flash unit actually trigger another external speedlight without firing the built-in flash at the same time?

I just downloaded the manual and from what I understand I would say yes but maybe somebody could confirm that? This is a feature I really really miss in the 5DII.

I don't have the 7D, but my understanding is that it has to flash to fire the external speedlites, but that it is just the pre-flash and doesn't affect the exposure. Hopefully someone else can verify as well.

... and does the wireless trigger allow high speed sync for the external speedlight

Yes, but it will fire a preflash to meter and actuate the slave flashes

( See also the video on the Digital Learning Center: EOS_7D-E-TTLFlash-CT )

IMO: yes, as that can be set independent on the flashunit(s), and works with the 580exII as Master or the ST-E2 as Master as well
