Its not hands on yet AFAIK but more details than on the yongnuo site.
I just sprung for these and YN-565EX on thephotogadget.com
the YN622 was only $98, the ones I saw on ebay were $10 more...
Yeah, I saw that already. I'd like to see some real hands on with it though. Would love to hear your opinion on it when you get it. It seems like a good option for me but as I said, I don't have the cash to just try it out. It needs to what I need it to. I had read somewhere that it wasn't going to have a test button but I'm glad to see it got added. Overall it seems like a good choice but we just need more info on it before we buy it.
