I use a Sunpak made " Lester Dine" ring/point light for my macro shots on my Nikon DSLRs. What is the trigger voltage for the Olympus camera ? Will I be able to use the ring light on it? It's a thyristor unit but has a power slider and has a "Manual", "Auto", and "TTL" switch as well. Not that I could ever use the TTL setting except with older film cameras. I changed out the dedicated foot from Nikon to the old single pin "Standard" foot years ago so that it would work without having to tape over excess pins. I assume it will work just fine on my Oly cameras as they can handle a trigger voltage of up to 24 volts and this unit is less than that. I will get out my trusty old digital multimeter to test it again just to be sure. I also have a Wein "Safe Sync" just in case. Does anyone else here use this unit?
