Jamie Flournoy, a San Francisco Bay area Realtor, who purchased Scott Hargis's Lighting Interiors eBook asked me this morning if she could use her Canon 580EX II with Pocket Wizards like Scott describes in the Figure 2.5 diagram (on pg 18 - click the image to the right for a larger view) that shows how he uses a pair of Pocket Wizards to fire one flash which intern fire a bunch of optical slaves flashes (SB-80s).
This is a great question and the answer is different for the Canon 580EXII than all other Canon flashes. The Canon 580EXII has a PC sync plug (unlike all other Canon flashes) so the answer to Jamie's question is YES, the Canon 580EXII will work as the flash that is connected to the Pocket Wizard in Scott's diagram.
But wait! What if you have an older Canon 580EX or any other Canon flash (which doesn't have a PC sync plug)? In that case the answer is NO, you have to have some extra gadgets. There are a couple of different alternatives:
Another related question, which no one has asked yet, but I can see coming is, "what if you have several older Canon EX flashes in your bag that you'd like to be able to use with Scott's technique and get the Canon flashes to trigger optically". You can do that too. Here's what you need:
There you go, everything you need to use those older Canon flashes with Scott's flash triggering technique. Thanks Jamie for raising this question. I'm sure others will have this issue too.
