A quick question I hope. Is the FL50 a really good flash? (Better then 600R) I've considered the FL600R some weeks, and just found FL50R to the same price as 600. It's priced so low that it confuses me. I can see at BH photo the 50 is the more expensive one, but not where I live. So is my locally dealer wrong, and I'm just about to get extremely lucky? Or is there different versions of the 50? And it will fit my E-M1?
