    So I have 2 of the vivitar 285hv and am trying to control them with the olympus fl-600r. I have tried several different controllers but cannot get them to sync with the camera flash. Does the olympus have a pre flash? If so is there some way to shut it off?

    Any use of TTL will use a pre-flash. That's how TTL works. :) Putting the mastering flash into Manual mode usually eliminates the pre-flash.

    What kind of "controllers" are you trying? The Vivitars have a proprietary sync port, so you can't just use, say, optical slaves that have PC or 3.5mm connectors.

    Make sure you don't have red eye reduction or RC mode turned on. Both of those will generate pre-flashes.
    I would try full manual mode at a modest sync speed to start with. TTL will not work well anyways if you have dumb slaves in the mix.

    Just for clarification, when you say controllers, what type of controller?

    Are you talking about optical slaves? For this you will need to fire a flash from the camera to trigger the slaves. Both 285HVs will need to be connected to a slave trigger. You will not be able to use TTL flash metering properly with the 285HVs any way since they don't support ttl operation, so you can just mount the fl600 on the e-m5 and set everything to manual and dial in the exposure via trial and error if you don't have a flash meter or don't want to to GN calculations.

    If you mean wireless radio triggers, this should work as long as a transmitter is on the e-m5 hot shoe, and all the flashes are connected to receivers (or at least one flash is connected to a receiver and the others to optical slaves.) Again, you'll be giving up TTL flash metering anyway, so just set everything to manual.

    Be sure to set the shutter speed on the e-m5 at or below the flash sync speed and you should be good to go once you've dialed in the ISO and an aperture to get the exposure you want.

    As has already been pointed out, if you are using optical slaves, set red-eye reduction to off if it isn't, and make sure you aren't using the high-speed sync(since this pulses the output from the fl600).
