I looked at this flash gun today and was informed it can be used off the camera (wireless mode) but the sales guy did not know if it gave full E-TTL or Autoflash with Automatic Ratio Control does anyone know?

I think it does everything! Couldn't they let you look at the manual in the shop? Maybe this link will help you.

To use off camera you need either another 550, or a ringflash MR14EX (and i'd guess the MR24EX) or ST-E2 on the camera. As far as I know you then have full e-ttl. To get ratio control you do of course need at least 2 flashes; both the st-e2 or 550 can set the ratio, i think using the ringflash gives less control.

Thanks for the link Benji, and the info Andrew I can see how it works now, wireless TTL flash when combined with ST-E2 Transmitter & multiple 550 EX's.

In my previous set-up I used an Olympus OM2n with two T32s, one on the power grip the other through the TTL cord this would allow a cordless set-up and may be a good solution for my macro work.
