Great flash. I have one and have used with my Hassy 500CM, Rollieflexes (TLRs and SL66) and SLR bodies such as Contax RTSII and my Nikon FM2 and F3. Big and a bit heavy but great handling and packs terrific power and punch. Got half a mind to grab this one for cheap $40 just to have if my other goes on me. Might just do that if still available in a couple days...
