I plan to use the above lights w/ the eos 3 for some portrait shots. I have Wein HS slave but it does NOT fit the 550ex. I have tried. Is there something else out there that I can use and cheap. I don't want to spend $$$ on the ST-E2 or another 550ex. I plan to hook the sync cord from the Photogenic to my EOS 3 and some how be able to sync this up (wireless) with the 550ex. Any input would be appreciated. Thanks.

There may be other ways to do this, but the most reliable way I know of is to use the Ikelite Lite-link TTL slave for the 550EX. If you set the 550EX on manual, the Lite-Link will just act like a very sensitive, regular optical slave. Of course it will do wireless TTL as well.

Adorama is selling them for $80.

In my opinion, you should make the 550EX the "wired" flash, and the Photogenic the "synced" flash. Does that make sense? The monolight already has a slave built in (it should anyway) so why try to make another (550EX) one fire that doesn't have one? I would use a hot shoe adapter that has a 1/4-20 tripod socket on the bottom for mounting the 550EX. Make sure you find one that has a pc cord on it. Then run a pc cord from the adapter attached to your flash back the camera. Use you Wein HS slave on the Photogenic if it needs it. Fire the 550EX with the camera and make the monloight the slave. Regardless of which one is the main or fill. I have a 550EX that I do the same thing with. It's a little difficult to slave the Canon flashes without the Ikelite lite link. I went the extra step and I use the ST-E2 to fire the 550EX which will fire any other flashes that I have slaves on. Cordless!! :) Or I use the cord from my Elan IIe and safe sync to the hot shoe adapter.
