A multi-purpose ring flash that fits on the front of any lens with a 49mm or 55mm filter size. It is suitable for almost all OM Zuiko lenses between 50mm and 200mm focal lenght, but especially useful with the range of OM System macro lenses.
The big breakthrough introduced by this unit was TTL Auto Flash. It also features eight built-in modeling lamps for compsing and focusing dark subjects. The modeling lamps are powered by the separate 6v Power Pack 2. Alternatively, both flash and modeling lamps can be powered together by the AC Adapter 3.
