National Camera Exchange has the Promaster 7500EDF Olympus Compatible TTL Flash for sale at $19.99. Free shipping at their ebay store, free shipping with $50 purchase at their direct website. (I've purchased several used lenses from Natcam, and they've been as good as or better than described, so I trust them... if you don't you can always buy through their ebay store and get ebay protection.) Note: Does not seem to work in TTL mode with Panasonic bodies. ebay link: Promaster 7500EDF Speedlight TTL Flash for Olympus E & PEN Cameras New 1110 National Camera Exchange Website link: CO PROMASTER 7500EDF OLYMPUS - National Camera Exchange manual: http://resources.dakiscdn.com/47d8f230-c025-0132-65de-00163e9110c0 (The link is a bit whacked direct from promaster's site, just rename the downloaded file to have a ".pdf" file extension and it'll open up in any PDF reader.) As of the posting of this message it looks like they still have 35 flash units left. I got mine earlier this week and tried it out with my Oly E-PM2 and it works well. TTL works, but the focus assist light doesn't (I've never really gotten that to ever work with any Oly flash either.) I tried it on my Pany G3 and it would not work in TTL mode... strange since all my Olympus brand flashes work fine with the Panasonic as does the one Metz flash that I have. It's definitely an older Promaster flash, so that's probably why it doesn't work with Panasonic bodies... it was probably manufactured prior to Panasonic really getting into the TTL flash supporting camera market. It's got some pretty high end features like a backlit display, auto-powered zoom, and a small flash in the front for fill flash. However, it's got so-so build quality, and my sample smelled like burnt plastic after trying several shots with my G3 (it was flashing at full power) and the top of the flash unit was VERY hot. I remember considering this flash way back when I had my Olympus SP-350 back in 2006 (they were around $150 a piece back then) since my FL-40 didn't work well with it. But just opted to go with the FL-36. Hey for $19.99 new, I grabbed one. It'll be my leave it in my car/work/"places where I won't leave my >$100 flashes" flash. If it were to go missing, I'd be more frustrated that my Eneloops in the flash were stolen more than the flash. :-O Edit: 04-04-2016 - Sold out.
