...now I also know why somebody calls the didicated SONY flash pseudo-TTL - it has obvoiusly the same pre-flash function as the built in flash! Intersting: No good in conjunction with studio flash set-ups. Thanks, Frantisek!

Thanks Frantisek - the answer I was hoping for. It works fine with external flash (AF280T in the hot shoe) + slave flash(es). I think the sync cord option is meant for dedicated flashes only - and i don't want to invest more in the SONY. But I admit to using it more than any other camera at the moment.

So it's no good for JB> digital portraits or things like that. For stills, it's fine, though (long JB> shutter speeds). Someone here might care to explain this digital flash JB> phenomenon to me? Digicams use pre-flash not true TTL to measure flash output. So your pop-up flash flashes a litte bit before the actual exposure to measure the scene, than flashes the full exposure. It's fault of the cameras, not flashes. The optical slave sees the first pre-flash, so it triggers, but that's actually before the main exposure. Either use synch cord (there should be some even for the 717, doesn't it? It does have a hotshoe), or use a specialised digital P&S optical slave, like one from Metz - it has settings to flash on second flash, ignoring the preflash. fra
