@PropilotBW , how do you like your Olympus flash (FL-600R)? I've been toying with the idea of getting one, but I'm not sure I really want to sink $250 into one when I feel like I'd get better use of that money saving up for a lens I really want.
I do like it. I mostly use it as a remote, off-camera flash in a one-light portrait setup. I trigger it by the small flash that my EM5ii came with. It produces some really nice results when I have the time to tinker with settings. I purchased a secondary Yongnuo 560-iv to supplement. While the Yongnuo could have done the exact same thing for a fraction of the cost, it is nice having the Olympus for on-camera usage(Sync).
*- I don't really care for flash photography, so I only use it when I need to. A lens is a much more fun way to spend the money.
