Okay. I don't shoot a ton of flash photos. I have the smaller of the two Oly 4/3 flashes (pre micro 43), and it has done fine, with the expected lesser reach and narrower coverage compared to the FL50 (the bigger of the two of that vintage). Looking at the aftermarket units out there, a lot of them seem to be different only in terms of labeling. The Godox, Promaster, K&F, even some of the Nissin units look to be the same pieces. Wondered if I could ask the collective for either device suggestions, or directions as to where to try to do research. Relatively light duty is anticipated. I like the idea of the Godox batttery pack, but I can buy a pretty good wad of NiMH AAs for the cost difference. Appreciate the help!
