I'm trying to sync my XTi to a 550ex speedlite with PC cord. I'm shopping on amazon.co.uk and can only find two adapters that might do the job; Hama or SC2. Will either of these do the job? If not can you suggest something (preferably something that's available in Europe and cheap-ish)
The hama one doesn't look like it has any electrical connections on top so I' sceptical about it.
The 550ex has a 3 pin socket on the side, is there a PC adapter for that?
