Hello This is quite confusing for me. I'm used to Nikon CLS system with my old D7000 and SB-600. I'm looking for something similar for my E-M10. I'm happy to slack on some demands, depending on price. First off, if I need a solution equivalent to the Nikon CLS (full automatic off-camera wireless), what will I be needing? I'm guessing the FL-600R and I'm good? Second, if I'm good with setting the flash output manually (not a problem), but still need wireless off-camera, what are my options here? At the moment I still have my SB-600 and a SC-28 cable - are those any good with my E-M10 or am I best served by selling those off? The SB-600 doesn't have a slave mode, like the SB-700/800/900. Thanks very much in advance!
