So I've got both a Panasonic G5, and Olympus E-M1. For flashes, I have the FL-600R, FL-300R, and 2 Promaster 7500EDFs (recently acquired for $20 each thanks to the Hot Deals forum), plus the FL-LM2 and the built in flash on the G5. Time for some radio triggers, I think! 1 Trigger and 2 Receivers (or 3 transceivers.) The FlashQ's look like a good mate for the general mu43 concept of cost effective, small and functional. But of course, no remote power control, etc. Cactus V6 is the only one I see that probably supports remote power adjustment, which might be nice. But a set of 3 costs more than a Yungnuo trigger, and 2 remote controllable flashes! Any suggestions? Anything to avoid?
