I am trying to decide between buying one Olympus FL-36 flash or two Vivitar 285HVs to use with my E-500. I want to experiment with off-camera flash, but i can also see myself using the flash on the camera for various events. The FL-36 has TTL functionality on camera with the E-500, the Vivitar does not. The FL-36 bounces _and_ swivels, the Vivitar only bounces. The FL-36 apparently has a slow recycle time. I think I could live without the TTL functions if I got the Vivitar, but it bugs me that it does not swivel for on-camera use. Is there a product available that will allow you to swivel a flash that does not swivel, ie. some sort of swiveling hot shoe mount that is itself a hot shoe to which you clip the flash and allow you to swivel?
