Hi, i've searched the net and the forum, but i'm not quite sure yet. I need a remote trigger for 2 lights; was using a PC sync cable with my 5D, but no sync out on the E-M5, plus wireless is more convenient. Will the Yongnuo RF-603II definitely work with the E-M5? Any other option out there i should consider in a similar price range? BTW, i'm in EU, so i would like to avoid ordering from the states. Thanks for the help, Daniele.
