Default Quantaray - MS-1 Wireless Flash Booster / Slave

Just bought a Olympus D-40. Was wondering if a slave flash unit would work with this camera since one cannot be attached to camera directly...?

Nearly all digicams have a TTL pre-flash that will fool nearly all slave units into firing before the shutter opens. This in turn fools the camera's exposure system (in automatic) and ironically causes dark exposures. http://www.srelectronics.com/ makes digital compatble slaves and flashes with built in slaves that will ignore the pre flash. I had to use an SA-10 with my Dimage camera until firmware upgrades allowed me to use the hot shoe sync connection. Not sure if anyone else makes digital compable slaves yet.
