EOS 7D or EOS 5D MkII?

To be clear, the pocket wizards are not needed. My response was early this am and my mind does not function before breakfast.

You would still need an additional 580EXII to be the master so thats $400.

Radio Poppers do wireless TTL. Canon also makes a wireless control modual, I think it's the SU-4? It's much cheaper than a 580EX II. An older 580EX can also control slave flashes.

The comment about the additional flash was to use the radio popper. It mounts to your flash, so you need one on the hothshoe.

The canon wireless module is the ST-E2 and it's back to line of sight flash at that point.
