I have aEOS 550D and a sunpak PZ42X flash. I want to get the flash off camera but the flash does not have wireless capabilities so I'm looking at a flash sync Cord. I found some on Ebay "Off Camera Flash sync Cable Cord E-TTL OC-E3 ".
One vendor says it's compatible with all manufacturers flash units...other vendors selling the same thing say it's compatible with speedlites but don't mention 3rd party flashes.
Can anyone recommend or advise if this will work or are there any other generic brands out there?
